Description

This module exploits a vulnerability in Adobe Flash Player versions 10.2.152.33
and earlier. This issue is caused by a failure in the ActionScript3 AVM2 verification
logic. This results in unsafe JIT(Just-In-Time) code being executed. This is the same
vulnerability that was used for the RSA attack in March 2011.

Specifically, this issue results in uninitialized memory being referenced and later
executed. Taking advantage of this issue relies on heap spraying and controlling the
uninitialized memory.

Currently this exploit works for IE6, IE7, and Firefox 3.6 and likely several
other browsers. DEP does catch the exploit and causes it to fail. Due to the nature
of the uninitialized memory its fairly difficult to get around this restriction.
