A guide to reporting security vulnerabilities in gems?

A little while ago after a discussion on the London Ruby U. Group
mailing
list [1] I tried and failed to find a concise guide to reporting
security
vulnerabilities in gems.

Recently, in an effort to plug this gap, I issued a pull request to the
Rubygems Guides [2] to address this.

Firstly, given that I feel that I know special knowledge in this area
and
have never reported a security vulnerability in a gem, I would really
appreciate your feedback on the proposed guide in the pull request.

Secondly in the guide I have suggested mailing this list with details of
the vulnerability. Do you think this is appropriate and if not where do
you
think would be a more appropriate place to post details of a
vulnerability?
