Astra Linux – Vulnerability in musl

The musl libc version up to 1.1.23 has an x87 floating-point stack adjustment imbalance, which is related to the math/i386/ directory. In some cases, using this library may lead to out-of-bounds writes, which are not present in an application’s source code...

Astra Linux – Vulnerability in musl

Musl libc versions 0.9.13 through 1.2.5 before 1.2.6 have a out-of-bounds write vulnerability, where an attacker can trigger the iconv conversion of untrusted EUC-KR text to UTF-8...

Astra Linux – Vulnerability in musl

A issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during the qsort function for very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 32-bi...

Astra Linux – Vulnerability in musl

In musl libc through 1.2.1, wcsnrtombs mishandles certain combinations of destination buffer size and source character limit, as demonstrated by an invalid write access buffer overflow...

DEBIAN-CVE-2026-56860

Previously, resolving relative paths containing parent directory '..' segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking f...
