The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a symlink following issue when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). A local user can create a symbolic link to an arbitrary file on the system, force the library to read it and perform a denial of service (DoS) attack.
