Fedora 35 SECURITY-UPDATE: Critical Podman DoS and Privilege Escalation

podman (Pod Manager) is a fully featured container engine that is a simple

daemonless tool. podman provides a Docker-CLI comparable command line that

eases the transition from other container engines and allows the management of

pods, containers and images. Simply put: alias docker=podman.

Most podman commands can be run as a regular user, without requiring

additional privileges.

podman uses Buildah(1) internally to create container images.

Both tools share image (not container) storage, hence each can use or

manipulate images (but not containers) created by the other.
