The one Spectrum executable to which I was referring (but didn't name)
when I said "apparently must be run as root" is "processd", not
"SpectroSERVER".

processd, which is an inetd-like process, must be run as root because
only a root-owned process can arbitrarily launch child processes that can
subsequently setuid(2) to become other users such as "spectrum".

I know of no one who normally runs SpectroSERVER as root, and do not claim
that it has anything to do with the aforementioned vulnerability.

As an aside:
My original posting to start this thread went to two mailing lists
simultaneously: "spectrum@po.cwru.edu" and "bugtraq.org".  Me thinks
that some of the replies in this thread may just be the result of folks
using a "group" reply feature (replying to all recipients) in their MUA
and were not (necessarily) meant for "bugtraq".

If nothing else, this can serve as a reminder to myself and others that
it may be better to compose seperate messages, one to each list.  That
way the other lists' address(es) won't appear in the message headers.
