I think the reasoning was that people on the -users list might
try to exploit it, whereas people on the -workers list are
trying to plug it; just a guess though.

For folks running 1.62 out of the box, here's what I think is the
quickest fix (as yet unverified but implemented):

cd ~majordom
chmod 000 wrapper 

edit the following files and change occurance of "$to" or "$reply_to"
to -t as stated in the note sent by John R:

majordomo.cf line 21
majordomo.pl line 225
resend line 326,328
new-list 40
request-answer 40

when done,

chmod 6775 wrapper

Please let me know if this is insufficient.
