'Name' => 'Adobe Flash Player copyPixelsToByteArray Method Integer Overflow',
'Description' => %q{
This module exploits an integer overflow in Adobe Flash Player. The vulnerability occurs
in the copyPixelsToByteArray method from the BitmapData object. The position field of the
destination ByteArray can be used to cause an integer overflow and write contents out of
the ByteArray buffer. This module has been tested successfully on:
* Windows 7 SP1 (32-bit), IE 8 to IE 11 and Flash 14.0.0.176, 14.0.0.145, and 14.0.0.125.
* Windows 7 SP1 (32-bit), Firefox 38.0.5 and Adobe Flash 14.0.0.179.
* Windows 8.1, Firefox 38.0.5 and Adobe Flash 14.0.0.179.
