runc is a CLI tool for spawning and running containers according to the OCI
specification. It was found that AppArmor can be bypassed when /proc
inside the container is symlinked with a specific mount configuration. This
issue has been fixed in runc version 1.1.5, by prohibiting symlinked
/proc. See PR #3785 for details. users are advised to upgrade. Users
unable to upgrade should avoid using an untrusted container image.
