high Nessus Plugin ID 267156

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-663536 advisory.

An integer overflow vulnerability exists in the Compound Document Binary File format parser of the GNOME Project G Structured File Library (libgsf) version v1.14.52. A specially crafted file can result in an integer overflow when processing the directory from the file that allows for an out-of-bounds index to be used when reading and writing to an array. This can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

Tenable has extracted the preceding description block directly from the Unity Linux 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 libgsf package.
