Debian dsa-5673 : glibc-doc - security update

high Nessus Plugin ID 193726

Language:

Synopsis

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

Description

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5673 advisory.

 - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the glibc-doc packages.
