|
|
|
|
|
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.
