Alpine: multiple podman packages: security update to 5.8.8-r0

medium Tenable Self-Hosted Container Security Plugin ID 448495

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A flaw was found in Podman. If an attacker can pass a crafted tar archive to the `podman load` command,
they can create files on the host machine with the privileges of the user running Podman. (CVE-2025-11395)

- A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout
header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary
file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer.
(CVE-2026-79699)

- A flaw was found in the buildah/copier Go package. When used outside of Buildah by a non-root caller, a
crafted tar archive containing malicious symlinks can escape the target extraction directory and create
files outside the intended destination. Buildah itself uses chroot hardening and is not affected.
(CVE-2026-79705)

Solution

Update the podman library and its related packages to version 5.8.8-r0 or later.
