Having just read that article, seems nothing more like guess work.

"security advisory"
"vulnerability researchers"

What are the definitions for these?

Most of the time the vendor discounts a finding as being nothing more than a bug. No security implications. Then 
someone else takes it and manages to do something with it that does have security implications. Then again, what is the 
definition of "security". For a vulnerability researcher, unless this is now a trade and a recognised job title with 
certification from some "school", who or what exactly is that?

Joe Six-Pack installs a piece of software, he finds that pressing 1,2,3 on the key board at the same time deletes his 
hard drive. Thinks that's mighty unusual. Tells Joe 12-Pack, who tells him there is some mailing list you can send bugs 
to called bugtraq, so he posts it there. Knows nothing about anything. Certainly isn't a "vulnerability researcher" and 
certainly hasn't posted a "security advisory". Doesn't know what he has and doesn't know what he is doing. Is the 
vendor going to come after them and sue them?

Then on the other hand, you have some major vendors who go out of their way to discount what a some else finds as being 
nothing more than a "bug", that someone else follows the procedures, creates what they think is a  ""security advisory" 
and nothing gets fixed. A series of insurmountable hurdles or mitigating factors make it a bug and not a security 
matter at all. Hurdles like being enticed to visit websites on the internet or being enticed to click on links in 
emails. Someone else may take that publicised info and re-work it so that the hurdles are overcome, it may be a 
succession of 10 individuals inputting each one step closer. Should all this be funnelled to the vendor when they've 
already dismissed the original as nothing more than bug?

Two bad examples but someone is going to have to define what a vulnerability is, what a security advisory is and what 
vulnerability researchers are.

The Responsible Disclosure Process draft specifically allows for
researchers to release vulnerability information if the vendor is not
sufficiently responsive.  Some people may disagree with the delay of
30 days between initial notification and release, but I don't think
there are good stats on how long it really takes vendors to fully
address vulnerability reports - open or closed source, freeware or
commercial.  Let's take a recent example - how much coordination had
to happen for the zlib vulnerability?  It seems reasonable to assume
that it took more than a day.  And the controversial "grace period"
has the interesting distinction of being used by both Microsoft and
Theo de Raadt.

Researchers can help to shed light in this area by publishing
disclosure histories along with their advisories.  (By the way, vendor
advisories rarely include such information.)

While the response to the proposal focused almost exclusively on how
it impacts researchers, it lays out a number of requirements for
vendors, primarily that they (a) make it easy for people to file
vulnerability reports, (b) be responsive to incoming vulnerability
reports, and (c) address the issues within a reasonable amount of
time.

IMHO, it makes a stronger impression when someone releases a security
advisory with an extensive disclosure history that says how much they
tried to resolve the issue with the vendor, before they released.

Those who are interested in the legal aspects of "responsible
disclosure" are encouraged to read the article by Mark Rasch at
http://online.securityfocus.com/columnists/66.  The article basically
says that the adoption of community standards could protect
researchers who disclose issues responsibly, while it could also help
vendors who seek legal recourse against researchers who are not
responsible (for some definition of "responsible").  The former could
happen with a community standard.  The latter may already be happening
without one.

This email is my personal opinion, not my employer's.
