Hi Marc,

You and your ilk obviously have to field accusations like the above
frequently, but repetition doesn't necessarily make something true.

Yes, even without cookbooks, master chefs can and do create extravagant
desserts -- but the rest of us novice bachelors just sort of stumble
around making a mess.

Would you say that the majority of viruses/worms are written by masters
or novices?

*Of course* explicit advisories help in the creation of exploits.  To
claim otherwise flies in the face of reality.  Aren't well-documented
libraries infinitely more useable than obscure, undocumented code?
The caveat is, as you mention, explicit advisories also help admins
audit our own networks *and* light a fire under the vendors to get a fix
out immediately.

I'd wager just about everyone on this list would agree that the benefits
of detailed advisories greatly outweigh the costs -- but it's a bit
naive to suggest that there /are no costs/.  Take another look at eEye's
AD20030910 advisory and reconsider from the perspective of a young
black-hat.

That said, both Full-Disclosure and eEye are infinitely valuable
resources for the good guys.  Keep up the great work.

take care,

Cael
