I don't think Apple has released a patch because ISC is till working out some tweaks with performance on high volume recursive servers.

From Paul Vixie, speaking for ISC:

UNTIL THE RELEASE OF THE -P2 CODE, IT IS IMPERATIVE THAT YOU RUN A -P1
VERSION OF BIND ON YOUR CACHING RESOLVERS. THE VULNERABILITY IS OF MORE
CONCERN THAN A SLOW SERVER.


Yes, there are performance issues with the current patch version of BIND to eliminate the DNS vulnerability, but that doesn't mean hide your head in the sand. The problems reported on the BIND-USERS mailing list are mainly identifying problems with some Linux systems (not all of them) and Solaris.

Also, most (if not all) of the problems lie with the absolutely newest version of BIND, 9.5.0. BIND has be patched for versions 9.3.5 and 9.4.2. Both of these are valid systems for running a DNS server. Let them work the bugs out of the 9.5.x version before you start trying to deploy it. MacOS X Server, version 10.5.4, is supplied with BIND 9.4.1-P1 (which is a version with the vulnerability). The deployment to fix this current problem should be 9.4.2-P1 and NOT the 9.5.0 line which is just past beta testing.

Who here immediately ran out and installed MacOS X 10.5, not 10.5.x, on their production systems when it first came out? Never mind, I don't really want to know. I don't ever implement a ".0" release of anything.

I'd like to set up a MacOS X test system with BIND 9.4.2-P1 and try and clobber it. Doing this is quite easy and the results could put to rest these types of statements.

Saying "someone has a problem" but not attempting to confirm the problem on the platform of interest, MacOS X in this case, is fear mongering, nothing less. It doesn't matter if it is Apple saying this or some individual on this list.
