I quote Diana from her original email that sparked this thread:

the case? If so, suggested workaround? Patch/upgrade coming?"

... and nobody else ever hears of the issue either. Why is this? It is
Because it appears that the current Mailman policy is to suppress
not just information, but also questions, about situations like this.

Nothing, assuming:
A) Makes it into the FAQ in a timely fashion for it to benefit site
admins
B) There is some means to notify site admins so that they don't
have to parse through mailman-users to get info on security issues.
I've been subscribed to mailman-announce for 5+ years. I don't
recall ever seeing anything such as: "FAQ XYZ has been updated", let
alone info on potential vulnerabilities that I should be aware of.

And that is good. Diana's case doesn't seem to meet that measure, yet
that is the advice Brad gave her. Was that an attempt to suppress this
info from other site admins?

Possibly, in a narrowly defined sense. I meant it as the rest of the
world uses it: http://www.answers.com/elitism
BTW, just who are the members of mailman-security?

And how does that apply to Diana's question? Clearly she was inquiring
about a fixed issue, right? If not, shouldn't the answer given to her
also be seen by others in similar situations?

Well it seems to there are two extremes in the Mailman group of
interested folks. Those that want to know everything, but don't want
anyone else to know it. And those that are expected to not know
anything until Barry/Tokio/Mark/ etc., tell them to know it. I just
think there is room for some middle ground.
There is more to Mailman than just users and developers. There are
those that are responsible for Mailman systems but they aren't the
day-to-day admins of the mailing lists. I think it is totally
irresponsible to expect that site admins find out on their own if there
are insecurities in the sites they run. If I am running a Mailman 2.1.6
site, I expect to be informed of vulnerabilities and security concerns
sometime before 2.1.7 is fully released, not just have to read it in the
CHANGES file of 2.1.7.
