openSUSE 16 Security Update : apptainer (openSUSE-SU-2026:20942-1)

medium Nessus Plugin ID 321006

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:20942-1 advisory.

 Changes in apptainer:

 - Update apptainer to version v1.5.1
 * Security fix (bsc#1267982):
 Fix for CVE-2026-48785 / GHSA-cr2j-534f-mf3g. Incorrect path matching for limit container paths directive. This is only applicable to SUID installations that have paths listed in limit container paths that are string prefixes of other paths which are not desired to be included in the list. For example, if /scratch is in the list but `/scratch2` also exists and contains container images, previously the latter would match but now only images under the exactly matching `/scratch` are included.

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 apptainer and / or apptainer-leap packages.
