4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Safari, which can be
exploited by malicious people to gain knowledge of sensitive
information.

The problem is that the "window.opener.location" in a popup window is
not read protected and can be exploited by a malicious website to e.g.
sniff on a users actions or to gain access to session IDs transferred
via the URL.

Successful exploitation requires e.g. that the user is tricked into
visiting a malicious website.
