Overview
Affected versions of this package are vulnerable to Privilege Context Switching Error via the allow.mount.nullfs option. An attacker can gain access to the host or parent jail's full filesystem by mounting directories via nullfs from within a jail when the allow.mount.nullfs option is enabled. This is only exploitable if the jail is configured to permit nullfs mounts from within the jail and the attacker has sufficient privileges inside the jail.
