medium Nessus Plugin ID 340431

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-2026-093172 advisory.

Integer overflow in the png_set_unknown_chunks function in libpng/pngset.c in libpng before 1.5.14beta08 allows context-dependent attackers to cause a denial of service (segmentation fault and crash) via a crafted image, which triggers a heap-based buffer overflow.

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 libpng12 package.
