DescriptionCVE.org
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.
