Description

The version of WINS (Windows Internet Name Service) installed on the remote Windows host is affected by a memory corruption vulnerability due to a logic error when handling a socket send exception.

By sending specially crafted packets to the affected WINS system, a remote attacker can potentially exploit this issue to execute arbitrary code as either SYSTEM on Windows 2003 or Local Service on Windows 2008 / 2008 R2.

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