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.
A flaw was found in runc. This vulnerability could allow a remote attacker to bypass security restrictions and create a symbolic link inside a container to the /proc directory, bypassing AppArmor and SELinux protections.
