Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2025:03462-1 advisory.

Update to Firefox Extended Support Release 140.3.1 ESR (bsc#1250452).

- Improved reliability when HTTP/3 connections fail: Firefox no longer forces HTTP/2 during fallback, allowing the server to choose the protocol and preventing stalls on some sites.

Tenable has extracted the preceding description block directly from the SUSE 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 packages.
