Description

This module exploits a vulnerability found in Microsoft Internet Explorer. A
use-after-free condition occurs when a CButton object is freed, but a reference
is kept and used again during a page reload, an invalid memory that's controllable
is used, and allows arbitrary code execution under the context of the user.

Please note: This vulnerability has been exploited in the wild targeting
mainly China/Taiwan/and US-based computers.
