Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS : libXpm vulnerability (USN-8862-1)

medium Nessus Plugin ID 362520

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8862-1 advisory.

 It was discovered that libXpm did not correctly handle XPM images with zero-dimension values. A local attacker could possibly use this issue to cause libXpm to use excessive resources, leading to a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected libxpm4 and / or xpmutils packages.
