17
          This module exploits a vulnerability in Adobe Flash Player versions 10.2.152.33
18
          and earlier. This issue is caused by a failure in the ActionScript3 AVM2 verification
19
          logic. This results in unsafe JIT(Just-In-Time) code being executed.  This is the same
20
          vulnerability that was used for the RSA attack in March 2011.
21

22
          Specifically, this issue results in uninitialized memory being referenced and later
23
          executed. Taking advantage of this issue relies on heap spraying and controlling the
24
          uninitialized memory.
25

26
          Currently this exploit works for IE6, IE7, and Firefox 3.6 and likely several
27
          other browsers. DEP does catch the exploit and causes it to fail. Due to the nature
28
          of the uninitialized memory its fairly difficult to get around this restriction.
