Details

runc AppArmor bypass with symlinked /proc ### 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.
