        This module exploits a NULL Pointer Dereference in win32k.sys, the vulnerability
        can be triggered through the use of TrackPopupMenu. Under special conditions, the
        NULL pointer dereference can be abused on xxxSendMessageTimeout to achieve arbitrary
        code execution. This module has been tested successfully on Windows XP SP3, Windows
        2003 SP2, Windows 7 SP1 and Windows 2008 32bits. Also on Windows 7 SP1 and Windows
        2008 R2 SP1 64 bits.
