'Name' => "MS14-012 Internet Explorer TextRange Use-After-Free",
'Description' => %q{
This module exploits a use-after-free vulnerability found in Internet Explorer. The flaw
was most likely introduced back in 2013, therefore only certain builds of MSHTML are
affected. In our testing with IE9, these vulnerable builds appear to be between
9.0.8112.16496 and 9.0.8112.16533, which implies August 2013 until early March 2014
(before the patch).
