Yesterday Apple released security update 2008-005 which was supposed to fix the DNS flaw I recently complained about Apple not having fixed yet. Well, it appears that Apple only half-fixed the problem. Yes, they have fixed the BIND DNS server in OS X, but in reality that only protects X-Serves running a DNS server. Sure, regular OS X ships with the BIND DNS server installed, but it’s not on by default, and almost no one turns it on. What we all use all the time is the stub resolver that’s part of OS X, and that’s what Apple didn’t fix. This means that regular Mac users are still not protected from this DNS flaw while just about everyone else is.
