Astra Linux – Vulnerability in libarchive

A vulnerability has been identified in the libarchive library, specifically within the archivereadformatrarseekdata function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, allowin...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in ksmbd within the Linux kernel versions 5.15 through 5.19, prior to 5.19.2. There is an out-of-bounds read and an OOPS error for SMB2write, when a large length is present in the zero DataOffset case. source-iocs-preserved const=SMB2WRITE...

Astra Linux – Vulnerability in TIF format

LibTIFF 4.4.0 contains an out-of-bounds read vulnerability in the writeSingleSection function located at line 7345 in the tools/tiffcrop.c file.

Astra Linux – Vulnerability in libstb

A issue was discovered in stbstbimage.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting them to RGBA format. This led to a buffer overflow when the result was re-interpreted as a 16-bit buffer. An attacker could potentially use stbimage to crash a service, o...
