A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary...

SUSE CVE-2026-56367

ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contains an integer overflow in the PSB PSD v2 RLE decoding path ReadPSDChannelRLE in coders/psd.c that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash...

CVE-2026-8358

A heap-based buffer overflow vulnerability was discovered in LibreOffice Calc's spreadsheet importer. When processing tracked changes from a spreadsheet document, the application fails to properly handle duplicate change identifiers. By reusing the same change identifier for two distinct types of...

kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...

GHSA-6V7P-G79W-8964 MessagePack for Python: Out-of-bounds read / crash on Unpacker reuse after a caught error

Impact If the Unpacker is used repeatedly after an error occurs, the process may crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack. Patches v1.2.1 Workarounds Users should create a new Unpacker instead of...

Astra Linux – Vulnerability in bind9

The code that processes control channel messages sent to named recursively calls certain functions during packet parsing. The recursion depth is limited only by the maximum acceptable packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack...

Astra Linux – Vulnerability in Firefox and Thunderbird

Drivers are not always robust against extremely large draw calls, and in some cases, this scenario could lead to crashes. This vulnerability affects Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4.1...

Astra Linux – Vulnerability in Qemu

A out-of-bounds write flaw was discovered in the UAS USB-attached SCSI device emulation in QEMU in versions prior to 6.2.0-rc0. The device uses the guest-provided stream number without proper checking, which can lead to out-of-bounds access to the UASDevice-data3 and UASDevice-status3 fields. A...

Astra Linux – Vulnerability in Policykit-1

A flaw was discovered in polkit. When processing an XML policy with 32 or more nested elements at depth, an out-of-bounds write vulnerability can be triggered. This issue may lead to a crash or other unexpected behavior, and arbitrary code execution is possible without being detected. To exploit...
