Add CVE-2013-3893 Internet Explorer SetMouseCapture Use-After-Free

This module exploits a use-after-free vulnerability that currents
targets Internet Explorer 9 on Windows 7, but the flaw should exist in
versions 6/7/8/9/10/11. It was initially found in the wild in Japan, but
other regions such as English, Chinese, Korean, etc, were targeted as
well.

The vulnerability is due to how the mshtml!CDoc::SetMouseCapture function
handles a reference during an event. An attacker first can setup two
elements, where the second is the child of the first, and then setup a
onlosecapture event handler for the parent element. The onlosecapture
event seems to require two setCapture() calls to trigger, one for the parent
element, one for the child. When the setCapture() call for the child element
is called, it finally triggers the event, which allows the attacker to cause
an arbitrary memory release using document.write(), which in particular frees
up a 0x54-byte memory. The exact size of this memory may differ based on the
version of IE. After the free, an invalid reference will still be kept and pass
on to more functions, eventuall this arrives in function
MSHTML!CTreeNode::GetInterface, and causes a crash (or arbitrary code execution)
when this function attempts to use this reference to call what appears to be a
PrivateQueryInterface due to the offset (0x00).

To mimic the same exploit found in the wild, this module will try to use the
same DLL from Microsoft Office 2007 or 2010 to leverage the attack.
