Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6737-1 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.
