Thanks for the explanation.  It would have helped if the message sent
to majordomo-workers explained the plans to repost it later on
majordomo-users.  Even better would have been to post an announcement
to majordomo-users saying something like:

   "A bug has been discovered (and is being actively exploited) that
   lets people run commands as the user that Majordomo runs under.
   Patches for 1.62 and 1.90 are being tested and a full announcement
   will be posted within 24 hours.  It might be prudent to disable
   Majordomo by [some simple method] pending availability of the
   patch."

That would have let us know what the risk was, what was being done
about it, and how to protect ourselves without disclosing the nature
of the bug itself.

-Dave
