Apple’s Security Update 2008-005 fixes that DNS glitch that has been freaking people out for the past few weeks. As such, it’s advised that you stop whatever you’re doing and apply the patch right now.
Some had accused Apple of dragging its feet in applying the patch, but now that it’s here, expert plenty of “what took Apple so long?” stories.
Bottom line, the hole has been shut. Apply the patch, or feel the Internet’s wrath. Maybe.
Or use OpenDNS. That’s fine way to avoid the DNS glitch, too.
