github.com/opencontainers/runc is vulnerable to sandbox restrictions bypass. An attacker who controls the container image for two containers that share a volume will be able to mount arbitrary volumes in a race condition during container initialization via a symlink that is added to the rootfs. This vulnerability allows a malicious container to mount /proc to another location within the attacker’s control and perform unauthorized writes to system files.
