Description:
codedreamer has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to disclose 
potentially sensitive information.

The vulnerability is caused due to an error in the handling of redirections for URLs with the "mhtml:" URI handler. 
This can be exploited to access documents served from another web site.
