Description:
sirdarckcat has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to conduct spoofing attacks.

The problem is that it is possible for a website to modify the location of another frame in another window by setting the location to an object instead of a string. This can be exploited to load malicious content into a frame of a trusted website.

This may be a variant of:
SA11966

The vulnerability is confirmed in IE7. Other versions may also be affected.

Solution:
Do not visit or follow links from untrusted websites.
