Description

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 an 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.
