Slander wasn't the correct word. It's just not a good idea to malign a
whole set of coders and programs without solid reasoning behind it.

This exploit is in minires, not dhcp3-server itself. [minires is a
library used by dhcp3-server to provide NSUPDATE used in Dynamic DNS.]

It also was found during an internal audit by ISC itself...

This is a DOS in dhcp3-relay, not in dhcp3-server itself.

Heh. There are bugs in it, but many of them have been characterized,
and they are typically fixed fairly rapidly. I can only remember a few
really nasty ones, but you'd only run into them in rather strange
setups.[1]

not reclaimed in the proper order [eg, oldest abandoned lease to
newest abandoned lease.] I only ran into it because I was operating on
a large network with pools at near capacity.
