A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.

Heap Buffer Overflow vulnerability in qpdf 11.9.0 allows attackers to crash the application via the std::__shared_count() function at /bits/shared_ptr_base.h.

A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.

Use after free in Canvas in Google Chrome prior to 123.0.6312.58 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

A double-free vulnerability was found in libdwarf. In a multiply-corrupted DWARF object, libdwarf may try to dealloc(free) an allocation twice, potentially causing unpredictable and various results.

The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An attacker must have physical access to the computer system and requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can allow for compromised card management operations during enrolment.

A use-after-free flaw was found in the Linux kernel's Memory Management subsystem when a user wins two races at the same time with a fail in the mas_prev_slot function. This issue could allow a local user to crash the system.

Use after free in Mojo in Google Chrome prior to 121.0.6167.160 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Heap buffer overflow in Skia in Google Chrome prior to 121.0.6167.160 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in Network in Google Chrome prior to 121.0.6167.139 allowed a remote attacker to potentially exploit heap corruption via a malicious file. (Chromium security severity: High)

Use after free in Canvas in Google Chrome prior to 121.0.6167.139 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in Peer Connection in Google Chrome prior to 121.0.6167.139 allowed a remote attacker to potentially exploit stack corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in Reading Mode in Google Chrome prior to 121.0.6167.85 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption via specific UI interaction. (Chromium security severity: Medium)

Use after free in Web Audio in Google Chrome prior to 121.0.6167.85 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in Passwords in Google Chrome prior to 121.0.6167.85 allowed a remote attacker to potentially exploit heap corruption via specific UI interaction. (Chromium security severity: Medium)

Out of bounds write in V8 in Google Chrome prior to 120.0.6099.224 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

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 heap use-after-free issue has been identified in SQLite in the jsonParseAddNodeArray() function in sqlite3.c. This flaw allows a local attacker to leverage a victim to pass specially crafted malicious input to the application, potentially causing a crash and leading to a denial of service.

Use after free in WebGPU in Google Chrome prior to 120.0.6099.199 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in WebAudio in Google Chrome prior to 120.0.6099.199 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Heap buffer overflow in ANGLE in Google Chrome prior to 120.0.6099.199 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Use after free in ANGLE in Google Chrome prior to 120.0.6099.199 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost.

Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer.

libcue provides an API for parsing and extracting data from CUE sheets. Versions 2.2.1 and prior are vulnerable to out-of-bounds array access. A user of the GNOME desktop environment can be exploited by downloading a cue sheet from a malicious webpage. Because the file is saved to `~/Downloads`, it is then automatically scanned by tracker-miners. And because it has a .cue filename extension, tracker-miners use libcue to parse the file. The file exploits the vulnerability in libcue to gain code execution. This issue is patched in version 2.3.0.
