The Samba Team reports:

• CVE-2020-27840: An anonymous attacker can crash the Samba AD DC LDAP server by sending easily crafted DNs as part of a bind request. More serious heap corruption is likely also possible.
• CVE-2021-20277: User-controlled LDAP filter strings against the AD DC LDAP server may crash the LDAP server.

Niels Möller reports:

I've prepared a new bug-fix release of Nettle, a low-level cryptographics library, to fix a serious bug in the function to verify ECDSA signatures. Implications include an assertion failure, which could be used for denial-of-service, when verifying signatures on the secp_224r1 and secp521_r1 curves.

Even when no assert is triggered in ecdsa_verify, ECC point multiplication may get invalid intermediate values as input, and produce incorrect results. [...] It appears difficult to construct an alleged signature that makes the function misbehave in such a way that an invalid signature is accepted as valid, but such attacks can't be ruled out without further analysis.

The OpenSSL project reports:

High: CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450)

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default.

High: NULL pointer deref in signature_algorithms processing (CVE-2021-3449)

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack.

The Apache SpamAssassin project reports:

Apache SpamAssassin 3.4.5 was recently released [1], and fixes an issue of security note where malicious rule configuration (.cf) files can be configured to run system commands.

In Apache SpamAssassin before 3.4.5, exploits can be injected in a number of scenarios. In addition to upgrading to SA 3.4.5, users should only use update channels or 3rd party .cf files from trusted places.

Simon Kelley reports:

[In configurations where the forwarding server address contains an @ character for specifying a sending interface or source address, the] random source port behavior was disabled, making cache poisoning attacks possible.

This only affects configurations of the form server=1.1.1.1@em0 or server=1.1.1.1@192.0.2.1, i. e. those that specify an interface to send through, or an IP address to send from, or use together with NetworkManager.

minio developer report:

This is a security issue because it enables MITM modification of request bodies that are meant to have integrity guaranteed by chunk signatures.

In a PUT request using aws-chunked encoding, MinIO ordinarily verifies signatures at the end of a chunk. This check can be skipped if the client sends a false chunk size that is much greater than the actual data sent: the server accepts and completes the request without ever reaching the end of the chunk + thereby without ever checking the chunk signature.

Phillip Lougher reports:

Integer overflow in the read_fragment_table_4 function in unsquash-4.c in Squashfs and sasquatch allows remote attackers to cause a denial of service (application crash) via a crafted input, which triggers a stack-based buffer overflow.

OpenBSD Project reports:

ssh-agent(1): fixed a double-free memory corruption that was introduced in OpenSSH 8.2 . We treat all such memory faults as potentially exploitable. This bug could be reached by an attacker with access to the agent socket.

On modern operating systems where the OS can provide information about the user identity connected to a socket, OpenSSH ssh-agent and sshd limit agent socket access only to the originating user and root. Additional mitigation may be afforded by the system's malloc(3)/free(3) implementation, if it detects double-free conditions.

The most likely scenario for exploitation is a user forwarding an agent either to an account shared with a malicious user or to a host with an attacker holding root access.

Node.js reports:

HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion (Critical) (CVE-2021-22883)

Affected Node.js versions are vulnerable to denial of service attacks when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.

DNS rebinding in --inspect (CVE-2021-22884)

Affected Node.js versions are vulnerable to a DNS rebinding attack when the whitelist includes "localhost6". When "localhost6" is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the "localhost6" domain. As long as the attacker uses the "localhost6" domain, they can still apply the attack described in CVE-2018-7160.

vault developers report:

Limited Unauthenticated License Read: We addressed a security vulnerability that allowed for the unauthenticated reading of Vault licenses from DR Secondaries.

Problem Description:

Due to a race condition in the jail_remove(2) implementation, it may fail to kill some of the processes.

Impact:

A process running inside a jail can avoid being killed during jail termination. If a jail is subsequently started with the same root path, a lingering jailed process may be able to exploit the window during which a devfs filesystem is mounted but the jail's devfs ruleset has not been applied, to access device nodes which are ordinarily inaccessible. If the process is privileged, it may be able to escape the jail and gain full access to the system.

Problem Description:

Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation.

Unfortunately, when running in HVM/PVH mode, the FreeBSD backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery.

Impact:

A malicious or buggy frontend driver may be able to cause resource leaks in the domain running the corresponding backend driver.

Problem Description:

A regression in the login.access(5) rule processor has the effect of causing rules to fail to match even when they should not. This means that rules denying access may be ignored.

Impact:

The configuration in login.access(5) may not be applied, permitting login access to users even when the system is configured to deny it.

Problem Description:

When a process, such as jexec(8) or killall(1), calls jail_attach(2) to enter a jail, the jailed root can attach to it using ptrace(2) before the current working directory is changed.

Impact:

A process with superuser privileges running inside a jail could change the root directory outside of the jail, thereby gaining full read and writing access to all files and directories in the system.

Redis Development team reports:

Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption.

(high) SECURITY-2195 / CVE-2021-22112

Privilege escalation vulnerability in bundled Spring Security library

The Asterisk project reports:

Given a scenario where an outgoing call is placed from Asterisk to a remote SIP server it is possible for a crash to occur.

The Asterisk project reports:

An unauthenticated remote attacker could replay SRTP packets which could cause an Asterisk instance configured without strict RTP validation to tear down calls prematurely.

The OpenSSL project reports:

Null pointer deref in X509_issuer_and_serial_hash() CVE-2021-23841

(Moderate) The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack.

Integer overflow in CipherUpdate CVE-2021-23840

(Low) Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash.

The Asterisk project reports:

If a registered user is tricked into dialing a malicious number that sends lots of 181 responses to Asterisk, each one will cause a 181 to be sent back to the original caller with an increasing number of entries in the "Supported" header. Eventually the number of entries in the header exceeds the size of the entry array and causes a crash.

The Asterisk project reports:

Due to a signedness comparison mismatch, an authenticated WebRTC client could cause a stack overflow and Asterisk crash by sending multiple hold/unhold requests in quick succession.

The Asterisk project reports:

When re-negotiating for T.38 if the initial remote response was delayed just enough Asterisk would send both audio and T.38 in the SDP. If this happened, and the remote responded with a declined T.38 stream then Asterisk would crash.

Minio developers report:

Thanks to @phith0n from our community upon a code review, discovered an SSRF (Server Side Request Forgery) in our Browser API implementation. We have not observed this report/attack in the wild or reported elsewhere in the community at large.

All users are advised to upgrade ASAP.

The target application may have functionality for importing data from a URL, publishing data to a URL, or otherwise reading data from a URL that can be tampered with. The attacker modifies the calls to this functionality by supplying a completely different URL or by manipulating how URLs are built (path traversal etc.).

In a Server-Side Request Forgery (SSRF) attack, the attacker can abuse functionality on the server to read or update internal resources. The attacker can supply or modify a URL which the code running on the server will read or submit data, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like HTTP enabled databases, or perform post requests towards internal services which are not intended to be exposed.

Problem Description:

Some OSes (including Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued.

As the queue is unbound, a guest may be able to trigger a OOM in the backend.

Problem Description:

Several file systems were not properly initializing the d_off field of the dirent structures returned by VOP_READDIR. In particular, tmpfs(5), smbfs(5), autofs(5) and mqueuefs(5) were failing to do so. As a result, eight uninitialized kernel stack bytes may be leaked to userspace by these file systems. This problem is not present in FreeBSD 11.

Additionally, msdosfs(5) was failing to zero-fill a pair of padding fields in the dirent structure, resulting in a leak of three uninitialized bytes.

Impact:

Kernel stack disclosures may leak sensitive information which could be used to compromise the security of the system.

The libpng project reports:

pngcheck versions 3.0.0 and earlier have a pair of buffer-overrun bugs related to the sPLT and PPLT chunks (the latter is a MNG-only chunk, but it gets noticed even in PNG files if the -s option is used). Both bugs are fixed in version 3.0.1, released on 24 January 2021. Again, while all known vulnerabilities are fixed in this version, the code is quite crufty, so it would be safest to assume there are still some problems hidden in there. As always, use at your own risk.

Jenkins Security Advisory:

Description

(Medium) SECURITY-2197 / CVE-2021-21615

Arbitrary file read vulnerability in workspace browsers

Todd C. Miller reports:

When invoked as sudoedit, the same set of command line options are now accepted as for sudo -e. The -H and -P options are now rejected for sudoedit and sudo -e which matches the sudo 1.7 behavior. This is part of the fix for CVE-2021-3156.

Fixed a potential buffer overflow when unescaping backslashes in the command's arguments. Normally, sudo escapes special characters when running a command via a shell (sudo -s or sudo -i). However, it was also possible to run sudoedit with the -s or -i flags in which case no escaping had actually been done, making a buffer overflow possible. This fixes CVE-2021-3156.

rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons.

Nokogiri reports:

In Nokogiri versions <= 1.11.0.rc3, XML Schemas parsed by Nokogiri::XML::Schema were trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks.

Michal Dardas from LogicalTrust reports:

The server in Chocolate Doom 3.0.0 and Crispy Doom 5.8.0 doesn't validate the user-controlled num_players value, leading to a buffer overflow. A malicious user can overwrite the server's stack.

Simon Kelley reports:

There are broadly two sets of problems. The first is subtle errors in dnsmasq's protections against the chronic weakness of the DNS protocol to cache-poisoning attacks; the Birthday attack, Kaminsky, etc.[...]

the second set of errors is a good old fashioned buffer overflow in dnsmasq's DNSSEC code. If DNSSEC validation is enabled, an installation is at risk.

The Go project reports:

The go command may execute arbitrary code at build time when cgo is in use on Windows. This may occur when running "go get", or any other command that builds code. Only users who build untrusted code (and don't execute it) are affected. In addition to Windows users, this can also affect Unix users who have "." listed explicitly in their PATH and are running "go get" or build commands outside of a module or with module mode disabled.

The P224() Curve implementation can in rare circumstances generate incorrect outputs, including returning invalid points from ScalarMult. The crypto/x509 and golang.org/x/crypto/ocsp (but not crypto/tls) packages support P-224 ECDSA keys, but they are not supported by publicly trusted certificate authorities. No other standard library or golang.org/x/crypto package supports or uses the P-224 curve.

cloud-init reports:

cloud-init release 20.4.1 is now available. This is a hotfix release, that contains a single patch to address a security issue in cloud-init 20.4.

Briefly, for users who provide more than one unique SSH key to cloud-init and have a shared AuthorizedKeysFile configured in sshd_config, cloud-init 20.4 started writing all of these keys to such a file, granting all such keys SSH access as root.

It's worth restating this implication: if you are using the default AuthorizedKeysFile setting in /etc/ssh/sshd_config, as most will be, then you are _not_ affected by this issue.

MoinMoin reports:

• Security fix for CVE-2020-25074: fix remote code execution via cache action

SO-AND-SO reports:

A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.

Node.js reports:

use-after-free in TLSWrap (High) (CVE-2020-8265)

Affected Node.js versions are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.

HTTP Request Smuggling in nodejs (Low) (CVE-2020-8287)

Affected versions of Node.js allow two copies of a header field in a http request. For example, two Transfer-Encoding header fields. In this case Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling.

OpenSSL - EDIPARTYNAME NULL pointer de-reference (CVE-2020-1971)

Todd C. Miller reports:

A potential information leak in sudoedit that could be used to test for the existence of directories not normally accessible to the user in certain circumstances. When creating a new file, sudoedit checks to make sure the parent directory of the new file exists before running the editor. However, a race condition exists if the invoking user can replace (or create) the parent directory. If a symbolic link is created in place of the parent directory, sudoedit will run the editor as long as the target of the link exists.If the target of the link does not exist, an error message will be displayed. The race condition can be used to test for the existence of an arbitrary directory. However, it _cannot_ be used to write to an arbitrary location.

CairoSVG security advisories:

When processing SVG files, the python package CairoSVG uses two regular expressions which are vulnerable to Regular Expression Denial of Service (REDoS).

The OpenSSL project reports:

EDIPARTYNAME NULL pointer de-reference (High)

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack.

JasPer NEWS:

Matrix developers reports:

A malicious or poorly-implemented homeserver can inject malformed events into a room by specifying a different room id in the path of a /send_join, /send_leave, /invite or /exchange_third_party_invite request. This can lead to a denial of service in which future events will not be correctly sent to other servers over federation. This affects any server which accepts federation requests from untrusted servers.

NLNetLabs reports:

Unbound and NSD when writing the PID file would not check if an existing file was a symlink. This could allow for a local symlink \ attack if an attacker has access to the user Unbound/NSD runs as.

The LibreSSL project reports:

Malformed ASN.1 in a certificate revocation list or a timestamp response token can lead to a NULL pointer dereference.

The p11-glue project reports:

CVE-2020-29363: Out-of-bounds write in p11_rpc_buffer_get_byte_array_value function

A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library. When the remote entity supplies a serialized byte array in a CK_ATTRIBUTE, the receiving entity may not allocate sufficient length for the buffer to store the deserialized value.

CVE-2020-29362: Out-of-bounds read in p11_rpc_buffer_get_byte_array function

A heap-based buffer over-read has been discovered in the RPC protocol used by thep11-kit server/remote commands and the client library. When the remote entity supplies a byte array through a serialized PKCS#11 function call, the receiving entity may allow the reading of up to 4 bytes of memory past the heap allocation.

CVE-2020-29361: Integer overflow when allocating memory for arrays of attributes and object identifiers

The Gitea Team reports for release 1.13.0:

• Add Allow-/Block-List for Migrate and Mirrors
• Prevent git operations for inactive users
• Disallow urlencoded new lines in git protocol paths if there is a port
• Mitigate Security vulnerability in the git hook feature
• Disable DSA ssh keys by default
• Set TLS minimum version to 1.2
• Use argon as default password hash algorithm
• Escape failed highlighted files

Problem Description:

When an ICMPv6 error message is received, the FreeBSD ICMPv6 stack may extract information from the message to hand to upper-layer protocols. As a part of this operation, it may parse IPv6 header options from a packet embedded in the ICMPv6 message.

The handler for a routing option caches a pointer into the packet buffer holding the ICMPv6 message. However, when processing subsequent options the packet buffer may be freed, rendering the cached pointer invalid. The network stack may later dereference the pointer, potentially triggering a use-after-free.

Impact:

A remote host may be able to trigger a read of freed kernel memory. This may trigger a kernel panic if the address had been unmapped.

Problem Description:

Two bugs exist in rtsold(8)'s RDNSS and DNSSL option handling. First, rtsold(8) failed to perform sufficient bounds checking on the extent of the option. In particular, it does not verify that the option does not extend past the end of the received packet before processing its contents. The kernel currently ignores such malformed packets but still passes them to userspace programs.

Second, when processing a DNSSL option, rtsold(8) decodes domain name labels per an encoding specified in RFC 1035 in which the first octet of each label contains the label's length. rtsold(8) did not validate label lengths correctly and could overflow the destination buffer.

Impact:

It is believed that these bugs could be exploited to gain remote code execution within the rtsold(8) daemon, which runs as root. Note that rtsold(8) only processes messages received from hosts attached to the same physical link as the interface(s) on which rtsold(8) is listening.

In FreeBSD 12.2 rtsold(8) runs in a Capsicum sandbox, limiting the scope of a compromised rtsold(8) process.

The X.org project reports:

These issues can lead to privileges elevations for authorized clients on systems where the X server is running privileged.

Insufficient checks on the lengths of the XkbSetMap request can lead to out of bounds memory accesses in the X server.

Insufficient checks on input of the XkbSetDeviceInfo request can lead to a buffer overflow on the head in the X server.

The HashiCorp team reports:

• artifact: Fixed a bug where interpolation can be used in the artifact destination field to write artifact payloads outside the allocation directory.
• template: Fixed a bug where interpolation can be used in the template source and destination fields to read or write files outside the allocation directory even when disable_file_sandbox was set to false (the default).
• template: Fixed a bug where the disable_file_sandbox configuration was only respected for the template file function and not the template source and destination fields.

The Gitea Team reports for release 1.12.6:

• Prevent git operations for inactive users
• Disallow urlencoded new lines in git protocol paths if there is a port

SaltStack reports multiple security vulnerabilities in Salt 3002:

• CVE-2020-16846: Prevent shell injections in netapi ssh client.
• CVE-2020-17490: Prevent creating world readable private keys with the tls execution module.
• CVE-2020-25592: Properly validate eauth credentials and tokens along with their ACLs. Prior to this change eauth was not properly validated when calling Salt ssh via the salt-api. Any value for 'eauth' or 'token' would allow a user to bypass authentication and make calls to Salt ssh.

The Go project reports:

A number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD) can panic when provided crafted large inputs. For the panic to happen, the divisor or modulo argument must be larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures). Multiple math/big.Rat methods are similarly affected.

The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code. This can be caused by a malicious gcc flags specified via a #cgo directive.

The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code. This can be caused by malicious unquoted symbol names.

The Apache Openofffice project reports:

CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in crafted documents

Description

A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.

Severity: Low

There are no known exploits of this vulnerability.

A proof-of-concept demonstration exists.

Thanks to the reporter for discovering this issue.

Acknowledgments

The Apache OpenOffice Security Team would like to thank Imre Rad for discovering and reporting this attack vector.

The Asterisk project reports:

If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.

The Asterisk project reports:

Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending upon some off nominal circumstances, and timing it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects were de-referenced, or accessed next by the initial creation thread.

KDE Project Security Advisory

Title	KDE Connect: packet manipulation can be exploited in a Denial of Service attack
Risk Rating	Important
CVE	CVE-2020-26164
Versions	kdeconnect <= 20.08.1
Author	Albert Vaca Cintora
Date	2 October 2020

Overview

An attacker on your local network could send maliciously crafted packets to other hosts running kdeconnect on the network, causing them to use large amounts of CPU, memory or network connections, which could be used in a Denial of Service attack within the network.

Impact

Computers that run kdeconnect are susceptible to DoS attacks from the local network.

Workaround

We advise you to stop KDE Connect when on untrusted networks like those on airports or conferences.

Since kdeconnect is dbus activated it is relatively hard to make sure it stays stopped so the brute force approach is to uninstall the kdeconnect package from your system and then run

	      kquitapp5 kdeconnectd
	  

Just install the package again once you're back in a trusted network.

Solution

KDE Connect 20.08.2 patches several code paths that could result in a DoS.

You can apply these patches on top of 20.08.1:

MITRE Corporation reports:

In GLPI before version 9.5.3, any authenticated user has read-only permissions to the planning of every other user, even admin ones. This issue is fixed in version 9.5.3. As a workaround, one can remove the caldav.php file to block access to CalDAV server.

Apache reports:

Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels, assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass invalid utf-8 strings to functions like pango_itemize.

Problem Description:

Affected Synapse versions assume that all events have an "origin" field set. If an event without the "origin" field is sent into a federated room, servers not already joined to the room will be unable to do so due to failing to fetch the malformed event.

Impact:

An attacker could cause a denial of service by deliberately sending a malformed event into a room, thus preventing new servers (and thus their users) from joining the room.

The Samba Team reports:

An unauthenticated attacker on the network can gain administrator access by exploiting a netlogon protocol flaw.

Python reports:

bpo-39603: Prevent http header injection by rejecting control characters in http.client.putrequest(…).

bpo-29778: Ensure python3.dll is loaded from correct locations when Python is embedded (CVE-2020-15523).

bpo-41004: CVE-2020-14422: The __hash__() methods of ipaddress.IPv4Interface and ipaddress.IPv6Interface incorrectly generated constant hash values of 32 and 128 respectively. This resulted in always causing hash collisions. The fix uses hash() to generate hash values for the tuple of (address, mask length, network address).

bpo-39073: Disallow CR or LF in email.headerregistry.Address arguments to guard against header injection attacks.

bpo-38576: Disallow control characters in hostnames in http.client, addressing CVE-2019-18348. Such potentially malicious header injection URLs now cause a InvalidURL to be raised.

bpo-39503: CVE-2020-8492: The AbstractBasicAuthHandler class of the urllib.request module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service. Fix the regex to prevent the catastrophic backtracking. Vulnerability reported by Ben Caller and Matt Schwager.

bpo-38945: Newline characters have been escaped when performing uu encoding to prevent them from overflowing into to content section of the encoded file. This prevents malicious or accidental modification of data during the decoding process.

bpo-38804: Fixes a ReDoS vulnerability in http.cookiejar. Patch by Ben Caller.

bpo-39017: Avoid infinite loop when reading specially crafted TAR files using the tarfile module (CVE-2019-20907).

bpo-41183: Use 3072 RSA keys and SHA-256 signature for test certs and keys.

bpo-39503: AbstractBasicAuthHandler of urllib.request now parses all WWW-Authenticate HTTP headers and accepts multiple challenges per header: use the realm of the first Basic challenge.

tt-rss project reports:

The cached_url feature mishandles JavaScript inside an SVG document.

imgproxy in plugins/af_proxy_http/init.php mishandles $_REQUEST["url"] in an error message.

It does not validate all URLs before requesting them.

Allows remote attackers to execute arbitrary PHP code via a crafted plural forms header.

The Nextcloud project reports:

NC-SA-2020-026 (low): Password of share by mail is not hashed when given on the create share call

A logic error in Nextcloud Server 19.0.0 caused a plaintext storage of the share password when it was given on the initial create API call.

Problem Description:

AMD and Intel CPUs support hardware virtualization using specialized data structures that control various aspects of guest operation. These are the Virtual Machine Control Structure (VMCS) on Intel CPUs, and the Virtual Machine Control Block (VMCB) on AMD CPUs. Insufficient access controls allow root users, including those running in a jail, to change these data structures.

Impact:

An attacker with host root access (including to a jailed bhyve instance) can use this vulnerability to achieve kernel code execution.

Node.js reports:

Updates are now available for v10,x, v12.x and v14.x Node.js release lines for the following issues.

HTTP Request Smuggling due to CR-to-Hyphen conversion (High) (CVE-2020-8201)

Affected Node.js versions converted carriage returns in HTTP request headers to a hyphen before parsing. This can lead to HTTP Request Smuggling as it is a non-standard interpretation of the header.

Impacts:

• All versions of the 14.x and 12.x releases line

Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests (Critical) (CVE-2020-8251)

Node.js is vulnerable to HTTP denial of service (DOS) attacks based on delayed requests submission which can make the server unable to accept new connections. The fix a new http.Server option called requestTimeout with a default value of 0 which means it is disabled by default. This should be set when Node.js is used as an edge server, for more details refer to the documentation.

Impacts:

• All versions of the 14.x release line

fs.realpath.native on may cause buffer overflow (Medium) (CVE-2020-8252)

libuv's realpath implementation incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.

Impacts:

• All versions of the 10.x release line
• All versions of the 12.x release line
• All versions of the 14.x release line before 14.9.0

Problem Description:

A ftpd(8) bug in the implementation of the file system sandbox, combined with capabilities available to an authenticated FTP user, can be used to escape the file system restriction configured in ftpchroot(5). Moreover, the bug allows a malicious client to gain root privileges.

Impact:

A malicious FTP user can gain privileged access to an affected system.

Problem Description:

A programming error in the ure(4) device driver caused some Realtek USB Ethernet interfaces to incorrectly report packets with more than 2048 bytes in a single USB transfer as having a length of only 2048 bytes.

An adversary can exploit this to cause the driver to misinterpret part of the payload of a large packet as a separate packet, and thereby inject packets across security boundaries such as VLANs.

Impact:

An attacker that can send large frames (larger than 2048 bytes in size) to be received by the host (be it VLAN, or non-VLAN tagged packet), can inject arbitrary packets to be received and processed by the host. This includes spoofing packets from other hosts, or injecting packets to other VLANs than the host is on.

Problem Description:

A number of AMD virtualization instructions operate on host physical addresses, are not subject to nested page table translation, and guest use of these instructions was not trapped.

Impact:

From kernel mode a malicious guest can write to arbitrary host memory (with some constraints), affording the guest full control of the host.

Version 5.9 contains security fix for L2TP clients and servers. Insufficient validation of incoming L2TP control packet specially crafted by unauthenticated user might lead to unexpected termination of the process. The problem affects mpd versions since 4.0 that brought in initial support for L2TP. Installations not using L2TP clients nor L2TP server configuration were not affected.

The GnuTLS project reports:

It was found by oss-fuzz that the server sending a "no_renegotiation" alert in an unexpected timing, followed by an invalid second handshake can cause a TLS 1.3 client to crash via a null-pointer dereference. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.

Manuel Pégourié-Gonnard reports:

When decrypting/authenticating (D)TLS record in a connection using a CBC ciphersuite without the Encrypt-then-Mac extension RFC 7366, Mbed TLS used dummy rounds of the compression function associated with the hash used for HMAC in order to hide the length of the padding to remote attackers, as recommended in the original Lucky Thirteen paper.

A local attacker who is able to observe the state of the cache could monitor the presence of mbedtls_md_process() in the cache in order to determine when the actual computation ends and when the dummy rounds start. This is a reliable target as it's always called at least once, in response to a previous attack. The attacker can then continue with one of many well-documented Lucky 13 variants.

Manuel Pégourié-Gonnard reports:

An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can recover the private keys used in RSA or static (finite-field) Diffie-Hellman operations.

Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour.

Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes is not trivial but likely possible for a dedicated attacker. The major hurdle for an attacker is that only every second byte is under their control with every first byte having a fixed value of 0x04.

Problem Description:

Due to improper mbuf handling in the kernel, a use-after-free bug might be triggered by sending IPv6 Hop-by-Hop options over the loopback interface.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

Problem Description:

When parsing option 119 data, dhclient(8) computes the uncompressed domain list length so that it can allocate an appropriately sized buffer to store the uncompressed list. The code to compute the length failed to handle certain malformed input, resulting in a heap overflow when the uncompressed list is copied into in inadequately sized buffer.

Impact:

The heap overflow could in principle be exploited to achieve remote code execution. The affected process runs with reduced privileges in a Capsicum sandbox, limiting the immediate impact of an exploit. However, it is possible the bug could be combined with other vulnerabilities to escape the sandbox.

Problem Description:

Due to improper handling in the kernel, a use-after-free bug can be triggered by sending large user messages from multiple threads on the same socket.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

The Go project reports:

When a Handler does not explicitly set the Content-Type header, both CGI implementations default to “text/html”. If an attacker can make a server generate content under their control (e.g. a JSON containing user data or an uploaded image file) this might be mistakenly returned by the server as “text/html”. If a victim visits such a page they could get the attacker's code executed in the context of the server origin.

Albert Astals Cid reports:

Overview

A maliciously crafted TAR archive containing symlink entries would install files anywhere in the user's home directory upon extraction.

Proof of concept

For testing, an example of malicious archive can be found at dirsymlink.tar

Impact

Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart.

Workaround

Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain symlink entries pointing outside the extraction folder.

The 'Extract' context menu from the Dolphin file manager shouldn't be used.

Solution

Ark 20.08.1 skips maliciously crafted symlinks when extracting TAR archives.

Alternatively, 8bf8c5ef07b0ac5e914d752681e470dea403a5bd can be applied to previous releases.

When chronyd is configured to save the pidfile in a directory where the chrony user has write permissions (e.g. /var/run/chrony - the default since chrony-3.4), an attacker that compromised the chrony user account could create a symbolic link at the location of the pidfile to make chronyd starting with root privileges follow the symlink and write its process ID to a file for which the chrony user doesn't have write permissions, causing a denial of service, or data loss.

bpo-39603: Prevent http header injection by rejecting control characters in http.client.putrequest(...).

curl security problems:

CVE-2020-8231: wrong connect-only connection

An application that performs multiple requests with libcurl's multi API and sets the CURLOPT_CONNECT_ONLY option, might in rare circumstances experience that when subsequently using the setup connect-only transfer, libcurl will pick and use the wrong connection - and instead pick another one the application has created since then.

CURLOPT_CONNECT_ONLY is the option to tell libcurl to not perform an actual transfer, only connect. When that operation is completed, libcurl remembers which connection it used for that transfer and "easy handle". It remembers the connection using a pointer to the internal connectdata struct in memory.

If more transfers are then done with the same multi handle before the connect-only connection is used, leading to the initial connect-only connection to get closed (for example due to idle time-out) while also new transfers (and connections) are setup, such a new connection might end up getting the exact same memory address as the now closed connect-only connection.

If after those operations, the application then wants to use the original transfer's connect-only setup to for example use curl_easy_send() to send raw data over that connection, libcurl could erroneously find an existing connection still being alive at the address it remembered since before even though this is now a new and different connection.

The application could then accidentally send data over that connection which wasn't at all intended for that recipient, entirely unknowingly.

Bftpd is vulnerable to out of bounds memory access, file descriptor leak and a potential buffer overflow.

The Apache httpd projec reports:

• mod_http2: Important: Push Diary Crash on Specifically Crafted HTTP/2 Header (CVE-2020-9490)
  
  A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards.

  When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools.

Problem Description:

When handling a 32-bit sendmsg(2) call, the compat32 subsystem copies the control message to be transmitted (if any) into kernel memory, and adjusts alignment of control message headers. The code which performs this work contained a time-of-check to time-of-use (TOCTOU) vulnerability which allows a malicious userspace program to modify control message headers after they were validated by the kernel.

Impact:

The TOCTOU bug can be exploited by an unprivileged malicious userspace program to trigger privilege escalation.

Problem Description:

A missing length validation code common to these three drivers means that a malicious USB device could write beyond the end of an allocated network packet buffer.

Impact:

An attacker with physical access to a USB port and the ability to bring a network interface up may be able to use a specially crafted USB device to gain kernel or user-space code execution.

The Go project reports:

Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This could lead to processing more input than expected when the caller is reading directly from the network and depends on ReadUvarint and ReadVarint only consuming a small, bounded number of bytes, even from invalid inputs.

sqlite3 update:

Various security issues could be used by an attacker to cause SQLite to crash, resulting in a denial of service, or possibly execute arbitrary code.

• CVE-2020-11655: SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled.
• CVE-2020-13434: SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.
• CVE-2020-13435: SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.
• CVE-2020-13630: ext/fts3/fts3.c in SQLite before 3.32.0 has a use-after-free in fts3EvalNextRow, related to the snippet feature.
• CVE-2020-13631: SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c.
• CVE-2020-13632: ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query.

Typo3 Team reports:

In case an attacker manages to generate a valid cryptographic message authentication code (HMAC-SHA1) - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the possibility to fetch typo3conf/LocalConfiguration.php which again contains the encryptionKey as well as credentials of the database management system being used. In case a database server is directly accessible either via internet or in a shared hosting network, this allows to completely retrieve, manipulate or delete database contents. This includes creating an administration user account - which can be used to trigger remote code execution by injecting custom extensions.

It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code (HMAC-SHA1) and can lead to various attack chains as described below.

Title:	Ark: maliciously crafted archive can install files outside the extraction directory.
Risk Rating:	Important
CVE:	CVE-2020-16116
Versions:	ark <= 20.04.3
Author:	Elvis Angelaccio
Date:	30 July 2020

Overview

A maliciously crafted archive with "../" in the file paths would install files anywhere in the user's home directory upon extraction.

Proof of concept

For testing, an example of malicious archive can be found at https://github.com/jwilk/traversal-archives/releases/download/0/relative2.zip

Impact

Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart

Workaround

Users should not use the 'Extract' context menu from the Dolphin file manager. Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain entries with "../" in the file path.

Solution

Ark 20.08.0 prevents loading of malicious archives and shows a warning message to the users.

Alternatively, https://invent.kde.org/utilities/ark/-/commit/0df592524fed305d6fbe74ddf8a196bc9ffdb92f can be applied to previous releases.

GitHub Advisory Database:

When a form page type is made available to Wagtail editors through the wagtail.contrib.forms app, and the page template is built using Django's standard form rendering helpers such as form.as_p (as directed in the documentation), any HTML tags used within a form field's help text will be rendered unescaped in the page. Allowing HTML within help text is an intentional design decision by Django; however, as a matter of policy Wagtail does not allow editors to insert arbitrary HTML by default, as this could potentially be used to carry out cross-site scripting attacks, including privilege escalation. This functionality should therefore not have been made available to editor-level users.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

The Apache Software Foundation reports:

An h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.

The payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.

A specially crafted sequence of HTTP/2 requests could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.

• Invalid tiled input file could cause invalid memory access TiledInputFile::TiledInputFile()

Micah Snyder reports:

CVE-2020-3350

Fixed a vulnerability a malicious user could exploit to replace a scan target's directory with a symlink to another path to trick clamscan, clamdscan, or clamonacc into removing or moving a different file (such as a critical system file). The issue would affect users that use the --move or --remove options for clamscan, clamdscan and clamonacc.

CVE-2020-3327

Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.3 that could cause a denial-of-service (DoS) condition. Improper bounds checking resulted in an out-of-bounds read that could cause a crash. The previous fix for this CVE in version 0.102.3 was incomplete. This fix correctly resolves the issue.

CVE-2020-3481

Fixed a vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3 that could cause a denial-of-service (DoS) condition. Improper error handling could cause a crash due to a NULL pointer dereference. This vulnerability is mitigated for those using the official ClamAV signature databases because the file type signatures in daily.cvd will not enable the EGG archive parser in affected versions.

Oracle reports:

This Critical Patch Update contains 40 new security patches for Oracle MySQL. 6 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The highest CVSS v3.1 Base Score of vulnerabilities affecting Oracle MySQL is 9.8.

This Pre-Release Announcement provides advance information about the Oracle Critical Patch Update for July 2020, which will be released on Tuesday, July 14, 2020.

NLNetLabs reports:

This release fixes CVE-2020-12662 and CVE-2020-12663.

Bug Fixes:

• CVE-2020-12662 Unbound can be tricked into amplifying an incoming query into a large number of queries directed to a target.
• CVE-2020-12663 Malformed answers from upstream name servers can be used to make Unbound unresponsive.

Problem Description:

The IPV6_2292PKTOPTIONS set handler was missing synchronization, so racing accesses could modify freed memory.

Impact:

A malicious user application could trigger memory corruption, leading to privilege escalation.

The WebKitGTK project reports vulnerabilities:

• CVE-2020-9802: Processing maliciously crafted web content may lead to arbitrary code execution.
• CVE-2020-9803: Processing maliciously crafted web content may lead to arbitrary code execution.
• CVE-2020-9805: Processing maliciously crafted web content may lead to universal cross site scripting.
• CVE-2020-9806: Processing maliciously crafted web content may lead to arbitrary code execution.
• CVE-2020-9807: Processing maliciously crafted web content may lead to arbitrary code execution.
• CVE-2020-9843: Processing maliciously crafted web content may lead to a cross site scripting attack.
• CVE-2020-9850: A remote attacker may be able to cause arbitrary code execution.
• CVE-2020-13753: CLONE_NEWUSER could potentially be used to confuse xdg- desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal’s input buffer.

Problem Description:

posix_spawnp spawns a new thread with a limited stack allocated on the heap before delegating to execvp for the final execution within that thread.

execvp would previously make unbounded allocations on the stack, directly proportional to the length of the user-controlled PATH environment variable.

Impact:

Long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of stack that was allocated, ultimately overflowing the heap-allocated stack with a direct copy of the value stored in PATH.

kramdown news:

CVE-2020-14001 is addressed to avoid problems when using the {::options /} extension together with the 'template' option.

Manuel Pégourié-Gonnard reports:

The scalar multiplication function in Mbed TLS accepts a random number generator (RNG) as an optional argument and, if provided, uses it to protect against some attacks.

It is the caller's responsibility to provide a RNG if protection against side-channel attacks is desired; however two groups of functions in Mbed TLS itself fail to pass a RNG:

1. mbedtls_pk_parse_key() and mbedtls_pk_parse_keyfile()
2. mbedtls_ecp_check_pub_priv() and mbedtls_pk_check_pair()

When those functions are called, scalar multiplication is computed without randomisation, a number of old and new attacks apply, allowing a powerful local attacker to fully recover the private key.

Gitlab reports:

The issue is that STUN/TURN response buffer is not initialized properly. (CWE 665) This is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client.

Drupal Security Team reports:

The Drupal core Form API does not properly handle certain form input from cross-site requests, which can lead to other vulnerabilities.

Ashley Newson reports:

The xrdp-sesman service can be crashed by connecting over port 3350 and supplying a malicious payload. Once the xrdp-sesman process is dead, an unprivileged attacker on the server could then proceed to start their own imposter sesman service listening on port 3350.

Discovered by Tony Yesudas.

Two vulnerabilities were fixed in the upstream repository:

• The bark_noise_hybridmp function allows remote attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact via a crafted file.
• mapping0_forward does not validate the number of channels, which allows remote attackers to cause a denial of service (heap-based buffer overflow or over-read) or possibly have unspecified other impact via a crafted file.

Simon Tatham reports:

[Release 0.74] fixes the following security issues:

• New configuration option to disable PuTTY's default policy of changing its host key algorithm preferences to prefer keys it already knows. (There is a theoretical information leak in this policy.) [CVE-2020-14002]
• In some situations an SSH server could cause PuTTY to access freed mdmory by pretending to accept an SSH key and then refusing the actual signature. It can only happen if you're using an SSH agent.

MITRE Corporation reports:

In GLPI before version 9.5.2, the `install/install.php` endpoint insecurely stores user input into the database as `url_base` and `url_base_api`. These settings are referenced throughout the application and allow for vulnerabilities like Cross-Site Scripting and Insecure Redirection Since authentication is not required to perform these changes,anyone could point these fields at malicious websites or form input in a way to trigger XSS. Leveraging JavaScript it's possible to steal cookies, perform actions as the user, etc. The issue is patched in version 9.5.2.

MITRE Corporation reports:

In GLPI before version 9.5.2, there is a SQL Injection in the API's search function. Not only is it possible to break the SQL syntax, but it is also possible to utilise a UNION SELECT query to reflect sensitive information such as the current database version, or database user. The most likely scenario for this vulnerability is with someone who has an API account to the system. The issue is patched in version 9.5.2. A proof-of-concept with technical details is available in the linked advisory.

MITRE Corporation reports:

In GLPI before version 9.5.2, there is a leakage of user information through the public FAQ. The issue was introduced in version 9.5.0 and patched in 9.5.2. As a workaround, disable public access to the FAQ.

MITRE Corporation reports:

In GLPI before version 9.5.2, the pluginimage.send.php endpoint allows a user to specify an image from a plugin. The parameters can be maliciously crafted to instead delete the .htaccess file for the files directory. Any user becomes able to read all the files and folders contained in /files/. Some of the sensitive information that is compromised are the user sessions, logs, and more. An attacker would be able to get the Administrators session token and use that to authenticate. The issue is patched in version 9.5.2.

MITRE Corporation reports:

In glpi before 9.5.1, there is a SQL injection for all usages of "Clone" feature. This has been fixed in 9.5.1.

MITRE Corporation reports:

In GLPI before version 9.5.2, when supplying a back tick in input that gets put into a SQL query,the application does not escape or sanitize allowing for SQL Injection to occur. Leveraging this vulnerability an attacker is able to exfiltrate sensitive information like passwords, reset tokens, personal details, and more. The issue is patched in version 9.5.2

curl security problems:

CVE-2020-8169: Partial password leak over DNS on HTTP redirect

libcurl can be tricked to prepend a part of the password to the host name before it resolves it, potentially leaking the partial password over the network and to the DNS server(s).

libcurl can be given a username and password for HTTP authentication when requesting an HTTP resource - used for HTTP Authentication such as Basic, Digest, NTLM and similar. The credentials are set, either together with CURLOPT_USERPWD or separately with CURLOPT_USERNAME and CURLOPT_PASSWORD. Important detail: these strings are given to libcurl as plain C strings and they are not supposed to be URL encoded.

In addition, libcurl also allows the credentials to be set in the URL, using the standard RFC 3986 format: http://user:password@host/path. In this case, the name and password are URL encoded as that's how they appear in URLs.

If the options are set, they override the credentials set in the URL.

Internally, this is handled by storing the credentials in the "URL object" so that there is only a single set of credentials stored associated with this single URL.

When libcurl handles a relative redirect (as opposed to an absolute URL redirect) for an HTTP transfer, the server is only sending a new path to the client and that path is applied on to the existing URL. That "applying" of the relative path on top of an absolute URL is done by libcurl first generating a full absolute URL out of all the components it has, then it applies the redirect and finally it deconstructs the URL again into its separate components.

This security vulnerability originates in the fact that curl did not correctly URL encode the credential data when set using one of the curl_easy_setopt options described above. This made curl generate a badly formatted full URL when it would do a redirect and the final re-parsing of the URL would then go bad and wrongly consider a part of the password field to belong to the host name.

The wrong host name would then be used in a name resolve lookup, potentially leaking the host name + partial password in clear text over the network (if plain DNS was used) and in particular to the used DNS server(s).

CVE-2020-8177: curl overwrite local file with -J

curl can be tricked by a malicious server to overwrite a local file when using -J (--remote-header-name) and -i (--include) in the same command line.

The command line tool offers the -J option that saves a remote file using the file name present in the Content-Disposition: response header. curl then refuses to overwrite an existing local file using the same name, if one already exists in the current directory.

The -J flag is designed to save a response body, and so it doesn't work together with -i and there's logic that forbids it. However, the check is flawed and doesn't properly check for when the options are used in the reversed order: first using -J and then -i were mistakenly accepted.

The result of this mistake was that incoming HTTP headers could overwrite a local file if one existed, as the check to avoid the local file was done first when body data was received, and due to the mistake mentioned above, it could already have received and saved headers by that time.

The saved file would only get response headers added to it, as it would abort the saving when the first body byte arrives. A malicious server could however still be made to send back virtually anything as headers and curl would save them like this, until the first CRLF-CRLF sequence appears.

(Also note that -J needs to be used in combination with -O to have any effect.)

Joel Esler reports:

• CVE-2018-15378:
  • Vulnerability in ClamAV's MEW unpacking feature that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
  • Reported by Secunia Research at Flexera.

  • An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the TOLOWER() macro for CHM decompression. Additionally, 0.100.2 reverted 0.100.1's patch for CVE-2018-14679, and applied libmspack's version of the fix in its place.

Apple reports:

• CVE-2019-8842: The ippReadIO function may under-read an extension.
• CVE-2020-3898: The ppdOpen function did not handle invalid UI constraint. ppdcSource::get_resolution function did not handle invalid resolution strings. An application may be able to gain elevated privileges.

CVE list:

GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated.

• MSA-17-0004: XSS in assignment submission page

Ruby on Rails blog:

Rails 6.0.3.2 has been released! This version of Rails contains an important security patch, and you should upgrade! The release contains only one patch that addresses CVE-2020-8185.

ISC reports:

An assertion check in BIND (that is meant to prevent going beyond the end of a buffer when processing incoming data) can be incorrectly triggered by a large response during zone transfer.

ISC reports:

The asterisk character ("*") is allowed in DNS zone files, where it is most commonly present as a wildcard at a terminal node of the Domain Name System graph. However, the RFCs do not require and BIND does not enforce that an asterisk character be present only at a terminal node.

A problem can occur when an asterisk is present in an empty non-terminal location within the DNS graph. If such a node exists, after a series of queries, named can reach an inconsistent state that results in the failure of an assertion check in rbtdb.c, followed by the program exiting due to the assertion failure.

lynis update:

This release resolves two security issues

• CVE-2020-13882 - Discovered by Sander Bos, code submission by Katarina Durechova
• CVE-2019-13033 - Discovered by Sander Bos

Thomas Guillem reports:

A heap-based buffer overflow in the hxxx_AnnexB_to_xVC function in modules/packetizer/hxxx_nal.c in VideoLAN VLC media player before 3.0.11 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a crafted H.264 Annex-B video (.avi for example) file.

Ben Caller and Matt Schwager reports:

Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking.

Python reports:

An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header.

Node.js reports:

Updates are now available for all supported Node.js release lines for the following issues.

TLS session reuse can lead to host certificate verification bypass (High) (CVE-2020-8172)

The 'session' event could be emitted before the 'secureConnect' event. It should not be, because the connection may fail to be authorized. If it was saved an authorized connection could be established later with the session ticket. Note that the https agent caches sessions, so is vulnerable to this.

The 'session' event will now only be emitted after the 'secureConnect' event, and only for authorized connections.

HTTP/2 Large Settings Frame DoS (Low) (CVE-2020-11080)

Receiving unreasonably large HTTP/2 SETTINGS frames can consume 100% CPU to process all the settings, blocking all other activities until complete.

The HTTP/2 session frame is limited to 32 settings by default. This can be configured if necessary using the maxSettings option.

napi_get_value_string_*() allows various kinds of memory corruption (High) (CVE-2020-8174)

Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer.

A exploit has not been reported and it may be difficult but the following is suggested:

• All users of LTS Node.js versions should update to the versions announced in this security post. This will address the issue for any non pre-built add-on.
• Maintainers who support EOL Node.js versions and/or build against a version of Node.js that did not support N-API internally should update to use the new versions of node-addon-api 1.x and 2.x that will be released soon after this announcement.

ICU-20958 Prevent SEGV_MAPERR in append (High) (CVE-2020-10531)

An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.

Fix was applied to 10.x in an abundance of caution, even though there is no known way to trigger the overflow in 10.x.

• This update resolves a use-after-free vulnerability that could lead to arbitrary code execution (CVE-2020-9633).

Problem Description:

If the push/pop level of the USB HID state is not restored within the processing of the same HID item, an invalid memory location may be used for subsequent HID item processing.

Impact:

An attacker with physical access to a USB port may be able to use a specially crafted USB device to gain kernel or user-space code execution.

CVE-2020-13254: Potential data leakage via malformed memcached keys

In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage. In order to avoid this vulnerability, key validation is added to the memcached cache backends.

CVE-2020-13596: Possible XSS via admin ForeignKeyRawIdWidget

Query parameters for the admin ForeignKeyRawIdWidget were not properly URL encoded, posing an XSS attack vector. ForeignKeyRawIdWidget now ensures query parameters are correctly URL encoded.

The GnuTLS project reports:

It was found that GnuTLS 3.6.4 introduced a regression in the TLS protocol implementation. This caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a MitM attacker to bypass authentication in TLS 1.3 and recover previous conversations in TLS 1.2.

nghttp2 security advisories:

The overly large HTTP/2 SETTINGS frame payload causes denial of service.

The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%.

• Fix missing authorization check on pull for public repos of private/limited org (#11656) (#11683)
• Use session for retrieving org teams (#11438) (#11439)

PowerDNS Team reports:

CVE-2020-10995: An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect.

CVE-2020-12244: An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer. This would allow an attacker in position of man-in-the-middle to send a NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.

CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker with enough privileges to change the system's hostname to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname is always null-terminated. Under some conditions this issue can lead to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution.

A vulnerability has been discovered in Sympa web interface by which attacker can execute arbitrary code with root privileges. Sympa uses two sorts of setuid wrappers:

• FastCGI wrappers
• newaliases wrapper

The FastCGI wrappers wwsympa-wrapper.fcgi and sympa_soap_server-wrapper.fcgi were used to make the web interface running under privileges of a dedicated user.

The newaliases wrapper (sympa_newaliases-wrapper) allows Sympa to update the alias database with root privileges.

Since these setuid wrappers did not clear environment variables, if environment variables like PERL5LIB were injected, forged code might be loaded and executed under privileges of setuid-ed users.

Drupal Security Team reports:

The jQuery project released version 3.5.0, and as part of that, disclosed two security vulnerabilities that affect all prior versions. As mentioned in the jQuery blog, both are: ... Security issues in jQuerys DOM manipulation methods, as in .html(), .append(), and the others. Security advisories for both of these issues have been published on GitHub.

Drupal 7 has an Open Redirect vulnerability. For example, a user could be tricked into visiting a specially crafted link which would redirect them to an arbitrary external URL. The vulnerability is caused by insufficient validation of the destination query parameter in the drupal_goto() function.

Hi everyone! Rails 5.2.4.3 and 6.0.3.1 have been released! These releases contain important security fixes, so please upgrade when you can.

Both releases contain the following fixes:

CVE-2020-8162: Circumvention of file size limits in ActiveStorage

CVE-2020-8164: Possible Strong Parameters Bypass in ActionPack

CVE-2020-8165: Potentially unintended unmarshalling of user-provided objects in MemCacheStore and RedisCacheStore

CVE-2020-8166: Ability to forge per-form CSRF tokens given a global CSRF token

CVE-2020-8167: CSRF Vulnerability in rails-ujs

Aki Tuomi reports:

Vulnerability Details: Sending malformed NOOP command causes crash in submission, submission-login or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: Send ``NOOP EE"FY`` to submission port, or similarly malformed command.

Vulnerability Details: Sending command followed by sufficient number of newlines triggers a use-after-free bug that might crash submission-login, submission or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: This can be currently reproduced with ASAN or Valgrind. Reliable way to crash has not yet been discovered.

Vulnerability Details: Sending mail with empty quoted localpart causes submission or lmtp component to crash. Risk: Malicious actor can cause denial of service to mail delivery by repeatedly sending mails with bad sender or recipient address. Steps to reproduce: Send mail with envelope sender or recipient as <""@example.org>. Workaround: For submission there is no workaround, but triggering the bug requires valid credentials. For lmtp, one can implement sufficient filtering on MTA level to prevent mails with such addresses from ending up in LMTP delivery.

Tobias Stöckmann reports:

F-Secure reports:

CVE-2020-11651 - Authentication bypass vulnerabilities

The ClearFuncs class processes unauthenticated requests and unintentionally exposes the _send_pub() method, which can be used to queue messages directly on the master publish server. Such messages can be used to trigger minions to run arbitrary commands as root.

The ClearFuncs class also exposes the method _prep_auth_info(), which returns the "root key" used to authenticate commands from the local root user on the master server. This "root key" can then be used to remotely call administrative commands on the master server. This unintentional exposure provides a remote un-authenticated attacker with root-equivalent access to the salt master.

CVE-2020-11652 - Directory traversal vulnerabilities

The wheel module contains commands used to read and write files under specific directory paths. The inputs to these functions are concatenated with the target directory and the resulting path is not canonicalized, leading to an escape of the intended path restriction.

The get_token() method of the salt.tokens.localfs class (which is exposed to unauthenticated requests by the ClearFuncs class) fails to sanitize the token input parameter which is then used as a filename, allowing insertion of ".." path elements and thus reading of files outside of the intended directory. The only restriction is that the file has to be deserializable by salt.payload.Serial.loads().

Ruby on Rails blog:

Due to an unfortunate oversight, Rails 4.2.11.2 has a missing constant error. To address this Rails 4.2.11.3 has been released.

Micah Snyder reports:

CVE-2020-3327: Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.2 that could cause a denial-of-service condition. Improper bounds checking of an unsigned variable results in an out-of-bounds read which causes a crash. Special thanks to Daehui Chang and Fady Othman for helping identify the ARJ parsing vulnerability.

CVE-2020-3341: Fixed a vulnerability in the PDF-parsing module in ClamAV 0.101 - 0.102.2 that could cause a denial-of-service condition. Improper size checking of a buffer used to initialize AES decryption routines results in an out-of-bounds read, which may cause a crash. OSS-Fuzz discovered this vulnerability.

Typo3 News:

CVE-2020-11063: TYPO3-CORE-SA-2020-001: Information Disclosure in Password Reset

It has been discovered that time-based attacks can be used with the password reset functionality for backend users. This allows an attacker to verify whether a backend user account with a given email address exists or not.

CVE-2020-11064: TYPO3-CORE-SA-2020-002: Cross-Site Scripting in Form Engine

It has been discovered that HTML placeholder attributes containing data of other database records are vulnerable to cross-site scripting. A valid backend user account is needed to exploit this vulnerability.

CVE-2020-11065: TYPO3-CORE-SA-2020-003: Cross-Site Scripting in Link Handling

It has been discovered that link tags generated by typolink functionality are vulnerable to cross-site scripting - properties being assigned as HTML attributes have not been parsed correctly.

CVE-2020-11066: TYPO3-CORE-SA-2020-004: Class destructors causing side-effects when being unserialized

Calling unserialize() on malicious user-submitted content can result in the following scenarios:

- trigger deletion of arbitrary directory in file system (if writable for web server)

- trigger message submission via email using identity of web site (mail relay)

Another insecure deserialization vulnerability is required to actually exploit mentioned aspects.

CVE-2020-11067: TYPO3-CORE-SA-2020-005: Insecure Deserialization in Backend User Settings

It has been discovered that backend user settings (in $BE_USER->uc) are vulnerable to insecure deserialization. In combination with vulnerabilities of 3rd party components this can lead to remote code execution. A valid backend user account is needed to exploit this vulnerability.

CVE-2020-11069: TYPO3-CORE-SA-2020-006: Same-Site Request Forgery to Backend User Interface

It has been discovered that the backend user interface and install tool are vulnerable to same-site request forgery. A backend user can be tricked into interacting with a malicious resource an attacker previously managed to upload to the web server - scripts are then executed with the privileges of the victims’ user session.

In a worst case scenario new admin users can be created which can directly be used by an attacker. The vulnerability is basically a cross-site request forgery (CSRF) triggered by a cross-site scripting vulnerability (XSS) - but happens on the same target host - thus, it’ actually a same-site request forgery (SSRF).

Malicious payload such as HTML containing JavaScript might be provided by either an authenticated backend user or by a non-authenticated user using a 3rd party extension - e.g. file upload in a contact form with knowing the target location.

The attacked victim requires an active and valid backend or install tool user session at the time of the attack to be successful.

Problem Description:

Requests to create cryptography sessions using a MAC did not validate the user-supplied MAC key length. The cryptodev module allocates a buffer whose size is this user-suppled length.

Impact:

An unprivileged process can trigger a kernel panic.

Problem Description:

The SCTP layer does improper checking when an application tries to update a shared key. Therefore an unprivileged local user can trigger a use-after- free situation, for example by specific sequences of updating shared keys and closing the SCTP association.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

Problem Description:

libalias(3) packet handlers do not properly validate the packet length before accessing the protocol headers. As a result, if a libalias(3) module does not properly validate the packet length before accessing the protocol header, it is possible for an out of bound read or write condition to occur.

Impact:

A malicious attacker could send specially constructed packets that exploit the lack of validation allowing the attacker to read or write memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

Problem Description:

The FTP packet handler in libalias incorrectly calculates some packet lengths. This may result in disclosing small amounts of memory from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

Impact:

A malicious attacker could send specially constructed packets that exploit the erroneous calculation allowing the attacker to disclose small amount of memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

Problem Description:

A race condition permitted a data structure in the kernel to be used after it was freed by the cryptodev module.

Impact:

An unprivileged process can overwrite arbitrary kernel memory.

Qutebrowser developers report:

After a certificate error was overridden by the user, qutebrowser displays the URL as yellow (colors.statusbar.url.warn.fg). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green (colors.statusbar.url.success_https). While the user already has seen a certificate error prompt at this point (or set content.ssl_strict to false which is not recommended), this could still provide a false sense of security.

MITRE Corporation reports:

inc/user.class.php in GLPI before 9.4.3 allows XSS via a user picture.

Mark Sapiro reports:

A content injection vulnerability via the options login page has been discovered and reported by Vishal Singh.

An issue similar to CVE-2018-13796 exists at different endpoint & param. It can lead to a phishing attack.

(added 2020-05-07) This is essentially the same as https://bugs.launchpad.net/mailman/+bug/1873722 except the vector is the private archive login page and the attack only succeeds if the list's roster visibility (private_roster) setting is 'Anyone'.

Jon Siwek of Corelight reports:

This release fixes the following security issues:

• Fix buffer over-read in Ident analyzer
• Fix SSL scripting error leading to uninitialized field access and memory leak
• Fix POP3 analyzer global buffer over-read
• Fix potential stack overflows due to use of Variable-Length-Arrays

Wagtail release notes:

CVE-2020-11037: Potential timing attack on password-protected private pages

This release addresses a potential timing attack on pages or documents that have been protected with a shared password through Wagtail's "Privacy" controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. (This is understood to be feasible on a local network, but not on the public internet.)

Cacti developer reports:

Lack of escaping of color items can lead to XSS exposure.

Webin security lab - dbapp security Ltd reports:

The TagLib::Ogg::FLAC::File::scan function in oggflacfile.cpp in TagLib 1.11.1 allows remote attackers to cause information disclosure (heap-based buffer over-read) via a crafted audio file.

VideoLAN reports:

Details

A remote user could:

• Create a specifically crafted image file that could trigger an out of bounds read
• Send a specifically crafter request to the microdns service discovery, potentially triggering various memory management issues

Impact

If successful, a malicious third party could trigger either a crash of VLC or an arbitratry code execution with the privileges of the target user.

While these issues in themselves are most likely to just crash the player, we can't exclude that they could be combined to leak user informations or remotely execute code. ASLR and DEP help reduce the likelyness of code execution, but may be bypassed.

We have not seen exploits performing code execution through these vulnerabilities

CVE-2019-19721 affects VLC 3.0.8 and earlier, and only reads 1 byte out of bound

Riccardo Schirone (https://github.com/ret2libc) reports:

In FullLoader python/object/new constructor, implemented by construct_python_object_apply, has support for setting the state of a deserialized instance through the set_python_instance_state method. After setting the state, some operations are performed on the instance to complete its initialization, however it is possible for an attacker to set the instance' state in such a way that arbitrary code is executed by the FullLoader.

This patch tries to block such attacks in FullLoader by preventing set_python_instance_state from setting arbitrar properties. It implements a blacklist that includes extend method (called by construct_python_object_apply) and all special methods (e.g. __set__, __setitem__, etc.).

Users who need special attributes being set in the state of a deserialized object can still do it through the UnsafeLoader, which however should not be used on untrusted input. Additionally, they can subclass FullLoader and redefine state_blacklist_regexp to include the additional attributes they need, passing the subclassed loader to yaml.load.

Howard Chu reports:

nested filters leads to stack overflow

Bleach developers reports:

bleach.clean behavior parsing style attributes could result in a regular expression denial of service (ReDoS).

Calls to bleach.clean with an allowed tag with an allowed style attribute are vulnerable to ReDoS. For example, bleach.clean(..., attributes={'a': ['style']}).

Oracle reports:

This Critical Patch Update contains 45 new security patches for Oracle MySQL. 9 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

Nextcloud reports:

XSS in Files PDF viewer (NC-SA-2020-019)

Missing ownership check on remote wipe endpoint (NC-SA-2020-018)

Problem Description:

Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognized signature algorithm is received from the peer.

Impact:

A malicious peer could exploit the NULL pointer dereference crash, causing a denial of service attack.

git security advisory reports:

Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. Many helpers will interpret this as matching any URL, and will return some unspecified stored password, leaking the password to an attacker's server.

Wagtail release notes:

CVE-2020-11001: Possible XSS attack via page revision comparison view

This release addresses a cross-site scripting (XSS) vulnerability on the page revision comparison view within the Wagtail admin interface. A user with a limited-permission editor account for the Wagtail admin could potentially craft a page revision history that, when viewed by a user with higher privileges, could perform actions with that user credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

git security advisory reports:

Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that contain an encoded newline can inject unintended values into the credential helper protocol stream, causing the credential helper to retrieve the password for one server for an HTTP request being made to another server, resulting in credentials for the former being sent to the latter.

NVD reports:

Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.

Problem Description:

Incomplete packet data validation may result in accessing out-of-bounds memory (CVE-2019-5614) or may access memory after it has been freed (CVE-2019-15874).

Impact:

Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results.

Twisted developers reports:

All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.

The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood). Thanks to Jonathan Looney and Piotr Sikora.

twisted.web.http was subject to several request smuggling attacks. Requests with multiple Content-Length headers were allowed (CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu for reporting this) and now fail with a 400; requests with a Content-Length header and a Transfer-Encoding header honored the first header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for reporting this) and now fail with a 400; requests whose Transfer-Encoding header had a value other than "chunked" and "identity" (thanks to ZeddYu Lu) were allowed and now fail with a 400.

The libssh team reports (originally reported by Yasheng Yang from Google):

A malicious client or server could crash the counterpart implemented with libssh AES-CTR ciphers are used and don't get fully initialized. It will crash when it tries to cleanup the AES-CTR ciphers when closing the connection.

The WebKitGTK project reports the following vulnerability.

Processing maliciously crafted web content may lead to arbitrary code execution or application crash (denial of service). Description: A memory corruption issue (use-after-free) was addressed with improved memory handling.

Borja Tarraso reports:

A flaw was found in Ansible 2.7.17 and prior, 2.8.9 and prior, and 2.9.6 and prior when using the Extract-Zip function from the win_unzip module as the extracted file(s) are not checked if they belong to the destination folder. An attacker could take advantage of this flaw by crafting an archive anywhere in the file system, using a path traversal. This issue is fixed in 2.10.

Borja Tarraso reports:

A flaw was found in Ansible 2.7.16 and prior, 2.8.8 and prior, and 2.9.5 and prior when a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.

Borja Tarraso reports:

A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.

Drupal Security Team reports:

The Drupal project uses the third-party library CKEditor, which has released a security improvement that is needed to protect some Drupal configurations.

Vulnerabilities are possible if Drupal is configured to use the WYSIWYG CKEditor for your site's users. An attacker that can createor edit content may be able to exploit this Cross Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, and this may include site admins with privileged access.

The latest versions of Drupal update CKEditor to 4.14 to mitigate the vulnerabilities.

Google Chrome Releases reports:

[1067851] Critical CVE-2020-6457: Use after free in speech recognizer. Reported by Leecraso and Guang Gong of Alpha Lab, Qihoo 360 on 2020-04-04

Lev Stipakov and Gert Doering report:

There is a time frame between allocating peer-id and initializing data channel key (which is performed on receiving push request or on async push-reply) in which the existing peer-id float checks do not work right.

If a "rogue" data channel packet arrives during that time frame from another address and with same peer-id, this would cause client to float to that new address.

The net effect of this behaviour is that the VPN session for the "victim client" is broken. Since the "attacker client" does not have suitable keys, it can not inject or steal VPN traffic from the other session. The time window is small and it can not be used to attack a specific client's session, unless some other way is found to make it disconnect and reconnect first.

The Squid developers reports:

Improper Input Validation issues in HTTP Request processing (CVE-2020-8449, CVE-2020-8450).

Information Disclosure issue in FTP Gateway (CVE-2019-12528).

Buffer Overflow issue in ext_lm_group_acl helper (CVE-2020-8517).

When parsing certain JSON documents, the json gem (including the one bundled with Ruby) can be coerced into creating arbitrary objects in the target system.

This is the same issue as CVE-2013-0269. The previous fix was incomplete, which addressed JSON.parse(user_input), but didn’t address some other styles of JSON parsing including JSON(user_input) and JSON.parse(user_input, nil).

See CVE-2013-0269 in detail. Note that the issue was exploitable to cause a Denial of Service by creating many garbage-uncollectable Symbol objects, but this kind of attack is no longer valid because Symbol objects are now garbage-collectable. However, creating arbitrary bjects may cause severe security consequences depending upon the application code.

Please update the json gem to version 2.3.0 or later. You can use gem update json to update it. If you are using bundler, please add gem "json", ">= 2.3.0" to your Gemfile.

The HAproxy Project reports:

The main driver for this release is that it contains a fix for a serious vulnerability that was responsibly reported last week by Felix Wilhelm from Google Project Zero, affecting the HPACK decoder used for HTTP/2. CVE-2020-11100 was assigned to this issue.

Google Chrome Releases reports:

This update contains 8 security fixes.

Apache Team reports:

SECURITY: CVE-2020-1934

mod_proxy_ftp: Use of uninitialized value with malicious backend FTP server.

SECURITY: CVE-2020-1927

rewrite, core: Set PCRE_DOTALL flag by default to avoid unpredictable matches and substitutions with encoded line break characters. The fix for CVE-2019-10098 was not effective.

The Cacti developers reports:

When guest users have access to realtime graphs, remote code could be executed (CVE-2020-8813).

Lack of escaping on some pages can lead to XSS exposure (CVE-2020-7106).

Remote Code Execution due to input validation failure in Performance Boost Debug Log (CVE-2020-7237).

The GnuTLS project reports:

It was found that GnuTLS 3.6.3 introduced a regression in the DTLS protocol implementation. This caused the DTLS client to not contribute any randomness to the DTLS negotiation breaking the security guarantees of the DTLS protocol.

MITRE Corporation reports:

In GLPI before version 9.5.0, the encryption algorithm used is insecure. The security of the data encrypted relies on the password used, if a user sets a weak/predictable password, an attacker could decrypt data. This is fixed in version 9.5.0 by using a more secure encryption library. The library chosen is sodium.

MITRE Corporation reports:

In GLPI after 0.68.1 and before 9.4.6, multiple reflexive XSS occur in Dropdown endpoints due to an invalid Content-Type. This has been fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI before version 9.4.6 there are multiple related stored XSS vulnerabilities. The package is vulnerable to Stored XSS in the comments of items in the Knowledge base. Adding a comment with content "alert(1)" reproduces the attack. This can be exploited by a user with administrator privileges in the User-Agent field. It can also be exploited by an outside party through the following steps: 1. Create a user with the surname `" onmouseover="alert(document.cookie)` and an empty first name. 2. With this user, create a ticket 3. As an administrator (or other privileged user) open the created ticket 4. On the "last update" field, put your mouse on the name of the user 5. The XSS fires This is fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI before version 9.4.6, there is a vulnerability that allows bypassing the open redirect protection based which is based on a regexp. This is fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI before 9.4.6, an attacker can execute system commands by abusing the backup functionality. Theoretically, this vulnerability can be exploited by an attacker without a valid account by using a CSRF. Due to the difficulty of the exploitation, the attack is only conceivable by an account having Maintenance privileges and the right to add WIFI networks. This is fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI from version 9.1 and before version 9.4.6, any API user with READ right on User itemtype will have access to full list of users when querying apirest.php/User. The response contains: - All api_tokens which can be used to do privileges escalations or read/update/delete data normally non accessible to the current user. - All personal_tokens can display another users planning. Exploiting this vulnerability requires the api to be enabled, a technician account. It can be mitigated by adding an application token. This is fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI before version 9.4.6, there is a SQL injection vulnerability for all helpdesk instances. Exploiting this vulnerability requires a technician account. This is fixed in version 9.4.6.

MITRE Corporation reports:

In GLPI after version 0.83.3 and before version 9.4.6, the CSRF tokens are generated using an insecure algorithm. The implementation uses rand and uniqid and MD5 which does not provide secure values. This is fixed in version 9.4.6.

The PostgreSQL project reports:

Versions Affected: 9.6 - 12

The ALTER ... DEPENDS ON EXTENSION sub-commands do not perform authorization checks, which can allow an unprivileged user to drop any function, procedure, materialized view, index, or trigger under certain conditions. This attack is possible if an administrator has installed an extension and an unprivileged user can CREATE, or an extension owner either executes DROP EXTENSION predictably or can be convinced to execute DROP EXTENSION.

Puppetlabs reports:

Puppet Server and PuppetDB provide useful performance and debugging information via their metrics API endpoints. For PuppetDB this may contain things like hostnames. Puppet Server reports resource names and titles for defined types (which may contain sensitive information) as well as function names and class names. Previously, these endpoints were open to the local network.

PE 2018.1.13 & 2019.4.0, Puppet Server 6.9.1 & 5.3.12, and PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and only allows /v2 access on localhost by default.

Puppetlabs reports:

Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master.

Puppet 6.13.0 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior.

Problem Description:

Incorrect use of a potentially user-controlled pointer in the kernel allowed vnet jailed users to panic the system and potentially execute aribitrary code in the kernel.

Impact:

Users with root level access (or the PRIV_NET_IFCREATE privilege) can panic the system, or potentially escape the jail or execute arbitrary code with kernel priviliges.

Problem Description:

When a TCP server transmits or retransmits a TCP SYN-ACK segment over IPv6, the Traffic Class field is not initialized. This also applies to challenge ACK segments, which are sent in response to received RST segments during the TCP connection setup phase.

Impact:

For each TCP SYN-ACK (or challenge TCP-ACK) segment sent over IPv6, one byte of kernel memory is transmitted over the network.

Problem Description:

The driver-specific ioctl(2) command handlers in oce(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.

Impact:

The oce(4) handler permits unprivileged users to send passthrough commands to device firmware.

Problem Description:

A missing NUL-termination check for the jail_set(2) configration option "osrelease" may return more bytes when reading the jail configuration back with jail_get(2) than were originally set.

Impact:

For jails with a non-default setting of children.max > 0 ("nested jails") a superuser inside a jail can create a jail and may be able to read and take advantage of exposed kernel memory.

Problem Description:

The driver-specific ioctl(2) command handlers in ixl(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.

Impact:

The ixl(4) handler permits unprivileged users to trigger updates to the device's non-volatile memory (NVM).

* ``bleach.clean`` behavior parsing embedded MathML and SVG content with RCDATA tags did not match browser behavior and could result in a mutation XSS.

Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or ``svg`` tags and one or more of the RCDATA tags ``script``, ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or ``xmp`` in the allowed tags whitelist were vulnerable to a mutation XSS.

* ``bleach.clean`` behavior parsing ``noscript`` tags did not match browser behavior.

Calls to ``bleach.clean`` allowing ``noscript`` and one or more of the raw text tags (``title``, ``textarea``, ``script``, ``style``, ``noembed``, ``noframes``, ``iframe``, and ``xmp``) were vulnerable to a mutation XSS.

Jon Siwek of Corelight reports:

This release addresses the following security issues:

• Potential Denial of Service due to memory leak in DNS TSIG message parsing.
• Potential Denial of Service due to memory leak (or assertion when compiling with assertions enabled) when receiving a second SSH KEX message after a first.
• Potential Denial of Service due to buffer read overflow and/or memory leaks in Kerberos analyzer. The buffer read overflow could occur when the Kerberos message indicates it contains an IPv6 address, but does not send enough data to parse out a full IPv6 address. A memory leak could occur when processing KRB_KDC_REQ KRB_KDC_REP messages for message types that do not match a known/expected type.
• Potential Denial of Service when sending many zero-length SSL/TLS certificate data. Such messages underwent the full Zeek file analysis treatment which is expensive (and meaninguless here) compared to how cheaply one can "create" or otherwise indicate many zero-length contained in an SSL message.
• Potential Denial of Service due to buffer read overflow in SMB transaction data string handling. The length of strings being parsed from SMB messages was trusted to be whatever the message claimed instead of the actual length of data found in the message.
• Potential Denial of Service due to null pointer dereference in FTP ADAT Base64 decoding.
• Potential Denial of Service due buffer read overflow in FTP analyzer word/whitespace handling. This typically won't be a problem in most default deployments of Zeek since the FTP analyzer receives data from a ContentLine (NVT) support analyzer which first null-terminates the buffer used for further FTP parsing.

Albert Astals Cid:

Okular can be tricked into executing local binaries via specially crafted PDF files.

This binary execution can require almost no user interaction.

No parameters can be passed to those local binaries.

We have not been able to identify any binary that will cause actual damage, be it in the hardware or software level, when run without parameters.

We remain relatively confident that for this issue to do any actual damage, it has to run a binary specially crafted. That binary must have been deployed to the user system via another method, be it the user downloading it directly as an email attachment, webpage download, etc. or by the system being already compromised.

MITRE CVE reports:

Django 1.11 before 1.11.29, 2.2 before 2.2.11, and 3.0 before 3.0.4 allows SQL Injection if untrusted data is used as a tolerance parameter in GIS functions and aggregates on Oracle. By passing a suitably crafted tolerance to GIS functions and aggregates on Oracle, it was possible to break escaping and inject malicious SQL.

Node.js reports:

Updates are now available for all active Node.js release lines for the following issues.

HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)

Affected Node.js versions can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system.

HTTP header values do not have trailing OWS trimmed (High) (CVE-2019-15606)

Optional whitespace should be trimmed from HTTP header values. Its presence may allow attackers to bypass security checks based on HTTP header values.

Remotely trigger an assertion on a TLS server with a malformed certificate string (High) (CVE-2019-15604)

Connecting to a NodeJS TLS server with a client certificate that has a type 19 string in its subjectAltName will crash the TLS server if it tries to read the peer certificate.

Strict HTTP header parsing (None)

Increase the strictness of HTTP header parsing. There are no known vulnerabilities addressed, but lax HTTP parsing has historically been a source of problems. Some commonly used sites are known to generate invalid HTTP headers, a --insecure-http-parser CLI option or insecureHTTPParser http option can be used if necessary for interoperability, but is not recommended.

SaltStack reports:

With the Salt NetAPI enabled in addition to having a SSH roster defined, unauthenticated access is possible when specifying the client as SSH.

Additionally, when the raw_shell option is specified any arbitrary command may be run on the Salt master when specifying SSH options.

nwtime.org reports:

Three ntp vulnerabilities, Depending on configuration, may have little impact up to termination of the ntpd process.

NTP Bug 3610: Process_control() should exit earlier on short packets. On systems that override the default and enable ntpdc (mode 7) fuzz testing detected that a short packet will cause ntpd to read uninitialized data.

NTP Bug 3596: An unauthenticated unmonitored ntpd is vulnerable to attack on IPv4 with highly predictable transmit timestamps. An off-path attacker who can query time from the victim's ntp which receives time from an unauthenticated time source must be able to send from a spoofed IPv4 address of upstream ntp server and and the victim must be able to process a large number of packets with the spoofed IPv4 address of the upstream server. After eight or more successful attacks in a row the attacker can either modify the victim's clock by a small amount or cause ntpd to terminate. The attack is especially effective when unusually short poll intervals have been configured.

NTP Bug 3592: The fix for https://bugs.ntp.org/3445 introduced a bug such that a ntp can be prevented from initiating a time volley to its peer resulting in a DoS.

All three NTP bugs may result in DoS or terimation of the ntp daemon.

Librsvg2 developers reports:

Backport the following fixes from 2.46.x:

Librsvg now has limits on the number of loaded XML elements, and the number of referenced elements within an SVG document. This is to mitigate malicious SVGs which try to consume all memory, and those which try to consume an exponential amount of CPU time.

Fix stack exhaustion with circular references in elements.

Fix a denial-of-service condition from exponential explosion of rendered elements, through nested use of SVG elements in malicious SVGs. This is similar to the XML "billion laughs attack" but for SVG instancing.

OpenSMTPD developers reports:

An out of bounds read in smtpd allows an attacker to inject arbitrary commands into the envelope file which are then executed as root. Separately, missing privilege revocation in smtpctl allows arbitrary commands to be run with the _smtpq group.

An unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem).

Janos Follath reports:

If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported.

The attack only requires access to fine grained measurements to cache usage. Therefore the attack might be applicable to a scenario where Mbed TLS is running in TrustZone secure world and the attacker controls the normal world or possibly when Mbed TLS is part of a hypervisor and the adversary has full control of a guest OS.

Qualys reports:

.

Qualys reports:

We discovered a minor vulnerability in OpenSMTPD, OpenBSD's mail server: an unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem).

Janos Follath reports:

Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it (as it is smaller than RSA keys and not guaranteed to have only large prime factors), and then, by brute force, recover the key.

The WeeChat project reports:

The WebKitGTK project reports multiple vulnerabilities.

Gitlab reports:

Incorrect membership handling of group sharing feature

Aki Tuomi reports:

lib-smtp doesn't handle truncated command parameters properly, resulting in infinite loop taking 100% CPU for the process. This happens for LMTP (where it doesn't matter so much) and also for submission-login where unauthenticated users can trigger it.

Aki also reports:

Snippet generation crashes if: message is large enough that message-parser returns multiple body blocks The first block(s) don't contain the full snippet (e.g. full of whitespace) input ends with '>'

Reno Robert reports:

FreeBSD uses a two-process model for running a VM. For booting non-FreeBSD guests, a modified grub-emu is used (grub-bhyve). Grub-bhyve executes command from guest grub.cfg file. This is a security problem because grub was never written to handle inputs from OS as untrusted. In the current design, grub and guest OS works across trust boundaries. This exposes a grub to untrusted inputs from guest.

grub-bhyve (emu) is built without SDL graphics support which reduces lot of gfx attack surface, however font loading code is still accessible. Guest can provide arbitrary font file, which is parsed by grub-bhyve running as root.

In grub-core/font/font.c, read_section_as_string() allocates section->length + 1 bytes of memory. However, untrusted section->length is an unsigned 32-bit number, and the result can overflow to malloc(0). This can result in a controlled buffer overflow via the 'loadfont' command in a guest VM grub2.cfg, eventually leading to privilege escalation from guest to host.

Reno Robert also reports:

GRUB supports commands to read and write addresses of choice. In grub-bhyve, these commands provide a way to write to arbitrary virtual addresses within the grub-bhyve process. This is another way for a guest grub2.cfg, run by the host, to eventually escalate privileges.

These vulnerabilities are mitigated by disabling the 'loadfont', 'write_dword', 'read_dword', 'inl', 'outl', and other width variants of the same functionality in grub2-bhyve.

There is also work in progress to sandbox the grub-bhyve utility such that an escaped guest ends up with nobody:nobody in a Capsium sandbox. It is not included in 0.40_8.

Mitre reports:

In libexif, there is a possible out of bounds write due to an integer overflow. This could lead to remote escalation of privilege in the media content provider with no additional execution privileges needed. User interaction is needed for exploitation.

Adobe reports:

• This update resolves a type confusion vulnerability that could lead to arbitrary code execution (CVE-2020-3757).

NGINX Team reports:

NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.

Upstream ksh93 maintainer Siteshwar Vashisht reports:

A flaw was found in the way ksh evaluates certain environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Services and applications that allow remote unauthenticated attackers to provide one of those environment variables could allow them to exploit this issue remotely.

Micah Snyder reports:

A denial-of-service (DoS) condition may occur when using the optional credit card data-loss-prevention (DLP) feature. Improper bounds checking of an unsigned variable resulted in an out-of-bounds read, which causes a crash.

MITRE CVE reports:

Django 1.11 before 1.11.28, 2.2 before 2.2.10, and 3.0 before 3.0.3 allows SQL Injection if untrusted data is used as a StringAgg delimiter (e.g., in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance, it was possible to break escaping and inject malicious SQL.

The libssh team reports:

In an environment where a user is only allowed to copy files and not to execute applications, it would be possible to pass a location which contains commands to be executed in additon.

When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of ssh_scp_new(), it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.

Oracle reports:

This Critical Patch Update contains 17 new security fixes for Oracle MySQL. 5 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

MariaDB reports:

Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.

The Apache SpamAssassin project reports:

A nefarious rule configuration (.cf) files can be configured to run system commands. This issue is less stealthy and attempts to exploit the issue will throw warnings.

Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.

Todd C. Miller reports:

Sudo's pwfeedback option can be used to provide visual feedback when the user is inputting their password. For each key press, an asterisk is printed. This option was added in response to user confusion over how the standard Password: prompt disables the echoing of key presses. While pwfeedback is not enabled by default in the upstream version of sudo, some systems, such as Linux Mint and Elementary OS, do enable it in their default sudoers files.

Due to a bug, when the pwfeedback option is enabled in the sudoers file, a user may be able to trigger a stack-based buffer overflow. This bug can be triggered even by users not listed in the sudoers file. There is no impact unless pwfeedback has been enabled.
