Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: erofs: Fixed a memory leak caused by LZMA global compressed deduplication. When testing microLZMA EROFS images with the new global compressed deduplication feature enabled -Ededupe, I discovered that some short-lived temporary...

Astra Linux – Vulnerability in busybox

An out-of-bounds heap read in Busybox’s unlzma applet leads to information leakage and denial of service when LZMA-compressed input is decompressed. This can be triggered by any applet/format that…...

Astra Linux – Vulnerability in imagemagick

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 vulnerability could occur due to a missing check. This issue has been fixed in versions...

BIT-LIBPYTHON-2026-15310 zipfile: bzip2/LZMA/Zstandard members decompress without a max_length bound, defeating chunked-read memory limits

When decompressing crafted zip files using the bzip/LZMA/Zstandard compressions, Python could use an attacker-controlled size to pre-allocate memory, possibly resulting in memory exhaustion...
