I just checked versiontracker.com and an Apple Software update was at the top of the list. it's also on Software Update. Here's the description:
This Security Update fixes potential vulnerabilities introduced in BIND, the domain server and client library software package from Internet Software Consortium (ISC), that is shipped with Mac OS X and Mac OS X Server. BIND version 8.3.4 addresses the recently-discovered potential vulnerabilities where an unauthorized person may disrupt the normal operation of the DNS name service. BIND is not activated by default on Mac OS X or Mac OS X Server.

I haven't restarted my computer since the day I installed 10.2.2 updates.
