Well, I would have to say it is definitely vulnerable to the first prob-
lem presented, as the BIND code is all the same, and the 2.2.1 release has
a BIND distro which falls within the version constraints of the exploit, that
it would have to be vulnerable. The second vulnerability however might not
apply to us. I haven't checked the gethostby* libs, so I'm not sure if the
resolver does internal bounds checking, rather than just letting you overflow
the stack with a spoofed DNS name. I will look into it this afternoon.
