Apple updated MacOS X and MacOS X Server to 10.5.4; time to update your systems. Now would be a good time to check out those security guides for MacOS X (10.3, 10.4, and 10.5) that Apple released early last month.
Also, if you missed it, the security distribution BackTrack released version 3 last month. BackTrack is a live CD Linux distribution focused on security and penetration testing: fix your systems before the attackers do it for you.
