        This exploit abuses an unpublished vulnerability in the HP-UX LPD
        service. This flaw allows an unauthenticated attacker to execute
        arbitrary commands with the privileges of the root user. The LPD
        service is only exploitable when the address of the attacking system
        can be resolved by the target. This vulnerability was silently patched
		with the buffer overflow flaws addressed in HP Security Bulletin HPSBUX0208-213.
