Good morning,

Today, I'm received alert from one of my friends regarding to
Vulnerability Note VU#800113 - Multiple DNS implementations vulnerable
to cache poisoning.
http://www.kb.cert.org/vuls/id/800113

I checked the above site, and found that most of the *BSD status are
unknown. Is this bug affected OpenBSD default bind dns?

I'm don't know either the above bug is similar to this thread or not.

looks like there is some work in progress to update the in-tree BIND
to 9.4.2-P1 + local tweaking, for example:

http://www.openbsd.org/cgi-bin/cvsweb/src/usr.sbin/bind/lib/dns/dispatch...

As Theo points out, patience is a virtue, and it's the "+ local
tweaking" above that is the reason I gratefully use OpenBSD.

I think named on OpenBSD 4.3 is affected too.

OpenBSD's named is affected.
It is a flow in the DNS protocol, which means potentially *all*
implementations are affected...

Credit where credit is due: djbdns isn't.

Without specifics on the issue, I can't tell if OpenBSD's bind is truly
vulnerable, but it certainly does use a fixed source port.

Stuart Henderson already answered this question on misc@ (12:10 UTC,
today). Named is vulnerable. The resolver is not :)

I'm just finish re-read it right now. Thank you for the input and I
agree that at this moment, we will waiting for the latest official
update from OpenBSD developers.

And probably a minor update for those who are deploying it over
Debian. Looks like it is time to patch it.

Have a nice day!
