Apple has released Security Update 2002-11-21 for Mac OS X 10.2 via the Software Update utility.

Potential vulnerabilities introduced in BIND – the domain server and client-library software from Internet Software Consortium (ISC), which is shipped with Mac OS X and Mac OS X Server – have been fixed.

The update fixes BIND version 8.3.4 and addresses the recently discovered potential vulnerabilities where an unauthorized person may disrupt the normal operation of the DNS (domain name server) service.

BIND is not activated by default on Mac OS X or Mac OS X Server.
