Summary
runc AppArmor bypass with symlinked /proc
Details

Impact

It was found that AppArmor, and potentially SELinux, can be bypassed when /proc inside the container is symlinked with a specific mount configuration.

Patches

Fixed in runc v1.1.5, by prohibiting symlinked /proc: https://github.com/opencontainers/runc/pull/3785

This PR fixes CVE-2023-27561 as well.

Workarounds

Avoid using an untrusted container image.
