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 11 with Flash 11, Flash 12 and Flash 13
|
|
over Windows XP SP3, Windows 7 SP1 and Windows 8.
