high Nessus Plugin ID 334466

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3536-1 advisory.

- CVE-2026-55686: specially crafted image where the `WORKDIR` path contains a symlink allows for directory creation and ownership modification on the host filesystem (bsc#1268579).
- CVE-2026-57231: specially crafted image can trick podman run into leaking host environment variables into the container (bsc#1269471).

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 podman, podman-docker, podman-remote and / or podmansh packages.
