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

: https://github.com/opencontainers/runc/pull/3785
This PR fixes CVE-2023-27561 as well.
Workarounds
Avoid using an untrusted container image.
