(somewhat) breaking the same-origin policy by undermining dns-pinning. This is the best technical explanation of the DNS rebinding attack I’ve seen. The linked demo worked for me in Safari but not in Camino.

Your browser is a tcp/ip relay. Thoroughly nasty new(ish) attack that breaks the same-domain policy and allows intranet content to be stolen by a malicious site. Using virtual hosts (hence requiring the Host: header) is the best known protection.
