Re: Holy Grail

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.
