        This module exploits a buffer overflow vulnerability in Adobe Flash Player. The
        vulnerability occurs in the flash.Display.Shader class, when setting specially
        crafted data as its bytecode, as exploited in the wild in April 2014. This module
        has been tested successfully on IE 6 to IE 10 with Flash 11 and Flash 12 over
        Windows XP SP3, Windows 7 SP1 and Windows 8.
