A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation.

The nftverdictinit() function allows positive values as drop error within the hook verdict, and hence the nfhookslow() function can cause a double free vulnerability when NFDROP is issued with a drop error which resembles NFACCEPT.

We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.

A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.

Description: Due to a buffer overflow bug Squid is vulnerable to a Denial of Service attack against HTTP Digest Authentication

Reference: https://github.com/squid-cache/squid/security/advisories/GHSA-phqj-m8gv-cq4g

Affected versions: 3.2.0.1-5.9, 6.0-6.3

A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service.

A Cross-site request forgery vulnerability exists in ipa/session/loginpassword in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.

A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.

A Local Privilege Escalation vulnerability (from any user to root) was found in polkit's pkexec, a SUID-root program that is installed by default on every major Linux distribution.

A flaw was found in grub2 in versions prior to 2.06. Setparamprefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.

A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. An attacker could use this flaw to crash or cause potential code execution in Go applications that use this library, under certain conditions, during GPG signature verification.

A flaw was found in the Serialization component of OpenJDK handled serialization filter. A process-wide filter could have been modified by setting jdk.serialFilter system property at runtime, possibly leading to a bypass of the intended filter during deserialization.

Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.

An out of bounds write flaw was found in the SQLite component of the Chromium browser.

A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

An out-of-bounds access issue was found in the Linux kernel, all versi ...

A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. This flaw allows an attacker to access the classloader.

In KDE Frameworks KConfig before 5.61.0, malicious desktop files and configuration files lead to code execution with minimal user interaction. This relates to libKF5ConfigCore.so, and the mishandling of .desktop and .directory files, as demonstrated by a shell command on an Icon line in a .desktop file.

A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.

Withdrawn Advisory This advisory has been withdrawn because the vulnerability only affects the Qpid Proton C library and not org.apache.qpid:proton-j. This link has been maintained to preserve external references.

Original Description

While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS even when configured to verify the peer certificate while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic.

A out of bounds access flaw was found in the font layout engine in the 2D component of OpenJDK. Missing validation of the position value in GlyphIterator::setCurrGlyphID could lead to memory corruption, triggered by a specially crafted font file. An untrusted Java application or applet could possibly use this flaw to bypass Java sandbox restrictions.

A flaw was found in the BigDecimal implementation in the Libraries component of OpenJDK. An untrusted numeric value parsed by a Java application could the application to use an excessive amount of CPU time.

A race condition was found in modauthdigest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.

A type confusion issue affecting multiple Apple products allows processing of maliciously crafted web content, leading to arbitrary code execution.

A vulnerability was found in modauthmellon before v0.14.2. If Apache is configured as a reverse proxy and modauthmellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication.
