Saying that this is IPv6 only is misleading.  The point of Mike's talk
was to show that buffer overflows do more than DOS or reset a Cisco box,
but they can actually be exploited like most things we learn about every
Patch Tuesday.

In the example he used in the talk, he showed off an exploit that took
advantage of a buffer overflow in the IPv6 code, but patching that one
bug does not mean you'll never see this type of exploit again.

Yes, any vendor big or small should realize that if they try to hide
things instead of fixing them and owning up, it's just a matter of time
until we find it for ourselves, and maybe next time the researcher will
be a black hat, also playing secret like Cisco.  

Imagine the PR bruise that will cause.

Purpose for posting it was, after reading it, there is not enough in my
opinion to warrant a nuclear lock down on this information. I did this to
sort of prove a point to those in the industry: "Stop letting vendors sell
you short." As an engineer they've (Cisco) shortchanged clients using
their equipment. If it's IPv6 based only, and not that big of a threat,
then they should see no problem with the information being released.

Before anyone decides to send in legal hounds, take note this is
searchable via Google... 5 minutes tops with over 100+ sites listing the
PDF. Sorry Cisco.

I find it rather funny, really.

Back in defcon, everybody was trading the presentation quietly and eagerly.

Then every kiddie started asking if anyone wants it.

Then we all got URL's to download it from.

Then there was another pass of "psst, want the Lynn presentation?"

And eventually, there was a CD placed on every table at defcon with the
presentation.

Seeing big-time secret-handshake groups take this with a whisper and a
"if I know you, email me and I might share it" was a bit silly.

Once again every Bad Guy in town had it and the Good Guys didn't want to
share under different excuses, some good, some sad.

I find that sharing the presentation openly on NANOG is a bit of a bad
move because of how some may perceive it and you, but it has become
completely silly not to do it. So I ask that people reserve judgment.. I
was very tempted to do it myself.
