Description

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.
