Secunia Research has reported a vulnerability, which affects most browsers. The vulnerability can be exploited by a malicious web site to hi-jack a named browser window, regardless of which web site is the true owner of the window.

The problem is that a website can inject content into another site's window if the target name of the window is known. This can e.g. be exploited by a malicious website to spoof the content of a pop-up window opened on a trusted website.
