github.com/containers/buildah is vulnerable to container escape. The vulnerability is due to improper Containerfile validation which allows a dummy image with a symbolic link to the host’s root filesystem as a mount source. This flaw enabling the mount operation to incorporate the host root filesystem inside the RUN step, thereby granting read-write access to the host filesystem and facilitating a full container escape during build time.
