Description

This module exploits an integer overflow vulnerability on Internet Explorer.
The vulnerability exists in the handling of the dashstyle.array length for vml
shapes on the vgx.dll module.

The exploit has been built and tested specifically against Windows 7 SP1 with
Internet Explorer 8. It uses either JRE6 or an information leak (to ntdll) to
bypass ASLR, and by default the info leak is used. To make sure the leak is
successful, the ntdll version should be either v6.1.7601.17514 (the default dll
version on a newly installed/unpatched Windows 7 SP1), or ntdll.dll v6.1.7601.17725
(installed after apply MS12-001). If the target doesn't have the version the exploit
wants, it will refuse to attack by sending a fake 404 message (webpage not found).

If you wish to try the JRE6 component instead to bypass ASLR, you can set the
advanced datastore option to 'JRE6'. If JRE6 is chosen but the target doesn't
have this particular component, the exploit will also refuse to attack by
sending a 404 message.
