CVE-2024-1753

A flaw was found in Buildah (and subsequently Podman Build) which allows
containers to mount arbitrary locations on the host filesystem into build
containers. A malicious Containerfile can use a dummy image with a symbolic
link to the root filesystem as a mount source and cause the mount operation
to mount the host root filesystem inside the RUN step. The commands inside
the RUN step will then have read-write access to the host filesystem,
allowing for full container escape at build time.
