Mac OS X DNS workaround failed

August 2nd, 2008 | No Comments | Posted in Security

The latest Mac OS X security update (2008-005) failed to fix (or temporarily solve) the DNS vulnerability in the client version of Mac OS X 10.5 and 10.4. The update solved (temporarily) the same problem in Mac OS X server, but somehow Apple forgot to update the client libraries. The source port is still not randomized (but incremented by 1 each time). So, is this really a critical problem? Or should we worry more about DNS servers behind NAT?
