        This module exploits a 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, when forcing a reallocation by copying more
        contents than the original capacity, but Flash forgets to update the domainMemory
        pointer, leading to a use-after-free situation when the main worker references the
        domainMemory again. This module has been tested successfully on Windows 7 SP1
        (32-bit), IE 8 and IE11 with Flash 17.0.0.134.
