JLSEC-2026-1013 ImageMagick: Heap Buffer Over-Write in MIFF encoder when using LZMA compression

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, when using LZMA compression in the MIFF encoder an out of bounds write can occur due to a missing check. This issue has been patched in versions 6.9.13-48 and...

PYSEC-2026-1831 pypdf can exhaust RAM via manipulated LZWDecode streams

Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream of a page using the LZWDecode filter. Patches This has been fixed in pypdf==6.1.3. Workarounds If you cannot upgrade yet, consider applying the changes from P...

OESA-2026-1853 xz security update

XZ Utils is free general-purpose data compression software with a high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils. Security Fixes: XZ Utils provide a general-purpose data-compression library...

JLSEC-2026-62

Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in...

AZL-64079 CVE-2025-6199 affecting package gdk-pixbuf2 for versions less than 2.42.10-4

A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the...

SUSE CVE-2025-5915

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber LZSS window. This means the library may attempt to read beyond the allocated memory buffer, which can...
