    That's a laudable intent.  Here's how I think it would have been 
better handled:

    * Get in touch with the administrators of the vulnerable host and 
help them to fix the problem in private, before anyone malicious has 
a chance to take advantage of the problem.
    * Mail, off-list, all of the addresses you can find in the 
archives from the affected host, warning them of the problem.  You 
could also try mailing the css-d administrator address to ask that we 
pass a message along to all affected accounts in the subscriber 
database.

The problem now is that, given the way you posted about this, you've 
potentially exposed a server vulnerability to the whole world, 
because all list messages are publicly archived.  Maybe that won't 
make any difference, but maybe it will.
    Ordinarily, I'd have sent this reply off-list, but I decided it 
was better to respond publicly and establish guidelines for the 
future.  I don't want to be a roadblock to improving security, but I 
also don't want to see security warnings on the list.  It's just the 
wrong venue, and there are (as I said above) other ways to handle 
such situations.
