high Nessus Plugin ID 235001

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dla-4143 advisory.

 ------------------------------------------------------------------------- Debian LTS Advisory DLA-4143-1 [email protected] https://www.debian.org/lts/security/ Sean Whitton April 30, 2025 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : glibc Version : 2.31-13+deb11u12 CVE ID : CVE-2025-0395

 A flaw was discovered in the implementation of the assert() function in the GNU C Library, the C standard library implementation used by Debian.

 When the assertion fails, the implementation does not allocate enough space for the assertion failure message string and size information, which may lead to a buffer overflow if the message string size aligns to page size.

 For Debian 11 bullseye, this problem has been fixed in version 2.31-13+deb11u12.

 We recommend that you upgrade your glibc packages.

 For the detailed security status of glibc please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/glibc

Solution

Upgrade the glibc-doc packages.
