"The version of WINS (Windows Internet Name Service) installed on the
remote Windows host is affected by a privilege escalation vulnerability.

By sending specially crafted packets to the loopback interface on an
affected WINS system, a local attacker can potentially exploit this
issue to execute arbitrary code and take complete control of the system.

Note that WINS is not installed by default on any of the affected
operating systems, although Nessus has determined it is on this host."
