Unity Linux 20.1070e Security Update: firefox (UTSA-2026-154031)

critical Nessus Plugin ID 380914

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-2026-154031 advisory.

Mozilla developers Bryce Seager van Dyk and the Mozilla Fuzzing Team reported potential vulnerabilities present in Firefox 101. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 102.

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 firefox package.
