Vendor Workaround
Do not use podman auto-update on untrusted containers or images. Before running an image, inspect its labels with podman image inspect --format '.Config.Labels' and verify that the io.containers.autoupdate and PODMAN_SYSTEMD_UNIT labels are not set. For existing containers, inspect their labels and ensure that auto-update labels are configured correctly and only present on containers intended to use auto-update.

| Description | A flaw was found in Podman. An attacker can trigger a Denial of Service (DoS) by supplying a container image containing crafted metadata labels. Podman's auto-update mechanism improperly trusts these image labels to determine which system services to restart. If a user runs the malicious container and auto-update processes it, arbitrary system services are restarted with the user's privileges, potentially allowing an attacker to shut down the host system when Podman runs with administrative privileges. | |
