high Nessus Plugin ID 323034

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2578-1 advisory.

This update for docker-stable fixes the following issues

- CVE-2026-33747: github.com/moby/buildkit: malicious frontends can craft API messages that cause files to be written outside of the BuildKit state directory (bsc#1260967).
- CVE-2026-33748: github.com/moby/buildkit: insufficient validation of Git URL fragment subdir components may allow access to files outside the checked-out Git repository (bsc#1261078).
- CVE-2026-33997: Fixed privilege validation bypass during plugin (bsc#1265907).
- CVE-2026-34040: Fixed Authz zero length regression (bsc#1265929).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected docker-stable and / or docker-stable-bash-completion packages.
