Uh, proofs only go so far. There was one Cornell CS professor who was a
real devotee of "proving" your programs correct. He even published one of
his proofs in a "refereed" journal. Big whoop. It still had an error.

Proofs can help identify flaws, but they can never rule out all flaws.
That's why their name is so bogus. I wouldn't be surprised if you could
prove that the Finger daemon, which is sort of like a really low-level
GET-ONLY HTTP server, is also safe. In fact, your math proving ability
could probably even prove the pre-Robert Morris finger daemon is safe and
secure. If programmers don't think of preventing finger requests longer
that 512 bytes then why should the head-in-the-clouds program provers?

on't speak
officially, were to be torn apart and the ulterior motives speculated   
upon,
I'd either shut up on this list or get off it completely. (Recall that we
had Marc Andreessen on this list last December--for whatever reasons, and
there are likely several, he left. I recall many attacks on his company.   
He
perhaps figured "What the hell do I need this for?")

Legitimate, scientific analysis is commendable. The brute force attack on
Netscape was great, and even better was the random seed attack. But many   
of
the attacks are less solid:

"How can you people at Digital Datawhack produce such crap? The   
assumptions
you make in the Flogisticon module are disgusting, another example of
security through obscenity."

(What I think this piling on is likely to accomplish is to push company
list subscribers here to just shut up. They see that the more is said by
folks from Netscape, as the best current example, the more fireworks and
insults ensue. The less that is said the better. This is not a good
situation.)

I'm not arguing for "niceness," just that some of the edge be taken off   
the
attacks.

The "bounties" that are being offered in press releases have the danger   
of
inviting premature announcement of results. And of discouraging companies
from actively participating in this list and discussing what might be   
done
to improve security.

Just my views. No doubt some will think I'm a shill for some company.
