|

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.
