[Mailman-Users] Handling MM security problems

[long post ahead]
This has gone past silly.
I run MM.
I'm concerned about security holes.
I want to know about holes ASAP.
I want to make the decision whether they are serious enough to stop all
list processing or to ignore.
I don't want someone else making these decisions for me.
The only way I'll know these things is if a Nice Person(tm) finds the
exploit and tells the people using and maintaining the software. It
would be great if I can get this info from the MM-user's list, but
if not, I'll get it somewhere else as surely the Bad Guys(tm) will.
Perhaps there needs to be a MM security discussion list for those of
us that care about it and actually read the code and the FAQs.

That's a rather direct threat, and -it- has no place on any civil list. "At
my own peril?" What is "my peril"?

...which makes it sound like this list is the mailman developer's private
sandbox, and they suffer the presence of the rest of us. May not be intended,
but that's one way to read it.

However, many of us are concerned about security bugs, and not only once
a patch has been created. We want to know when they are discovered. It
this info isn't available here, then we will get it somewhere else, and
will wonder if the MM developers know or care about it.

Yes, and we the readers have an expectation that we can discuss all
aspects of the software & its usage.

Unless the -cabel members include the original poster in their discussion,
there is little utility for us unwashed folks to post to that list. It
becomes a black hole. See below.

And -that- is telling us what to do elsewhere, which doesn't square with
statements above and with industry practice.

I'm also getting a little grumpy because the discussion has moved from a
civil discussion of "please don't to that, here's why" level to a do that
"at your peril" level.
I'll climb out a limb and suggest what I just asked chuq:
If you find a security problem, please tell the cabal. We'll get back to
you within 12 hours. If we do, please don't post this directly to the
MM-users list. If we don't say anything, in the interest of protecting
sites using MM, publicly identify the problem. Please don't publish your
own patches unless the problem is so bad that it compromises the operation
of entire servers. If you do have a patch, please send it to the MM
developers, we may use it directly.
