'Description' => %q{
|
|
|
|
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.
