Mr.Niega has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in inetcomm.dll when processing URLs with the "mhtml:" URI handler. This can be exploited to cause a stack-based buffer overflow via an overly long URL by e.g. tricking a user into visiting a malicious web site with Internet Explorer or opening a specially crafted Internet shortcut.

Successful exploitation allows execution of arbitrary code.
