Unity Linux 20.1070e Security Update: libtiff (UTSA-2025-680617)

medium Nessus Plugin ID 267708

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-2025-680617 advisory.

 A stack buffer overflow flaw was found in Libtiffs' tiffcp.c in main() function. This flaw allows an attacker to pass a crafted TIFF file to the tiffcp tool, triggering a stack buffer overflow issue, possibly corrupting the memory, and causing a crash that leads to a denial of service.

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 libtiff package.
