A flaw was found in buildah where containers were incorrectly started with non-empty default permissions. A bug was found in Moby (Docker Engine) where containers were incorrectly started with non-empty inheritable Linux process capabilities, enabling an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. This has the potential to impact confidentiality and integrity.

A vulnerability was found in `podman build` and `buildah.` This issue occurs in a container breakout by using --jobs=2 and a race condition when building a malicious Containerfile. SELinux might mitigate it, but even with SELinux on, it still allows the enumeration of files and directories on the host.

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.

The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.

A flaw was found in the github.com/containers/image library. This flaw allows attackers to trigger unexpected authenticated registry accesses on behalf of a victim user, causing resource exhaustion, local path traversal, and other attacks.
