I made a call to DG, and the person I spoke with said "That's why it's
commented out, with a warning about security"

So....I reposted the message to the DGUSERS mailing list, and got the following
response.  We are in the midst of preparing for the upgrade, so I can't verify
it.

As stated below...apparently it's fixed in MU03.  FWIW, DG/UX is officially up
to 4.11MU04,with 4.20 coming soon.

This was posted on the BUGTRAQ(large distribution among the security AND
hacking communities) mailing list the other day....A HUGE security hole in
DGUX's finger.  A call to DGUX resulted in a "well...that's why it's commented
out by default"... :(

I'm in the process of submitting an RFE with DG, but I don't have a lot of
hope.

Brian - FYI - This problem is fixed in revision R4.11MU03 and later of DG/UX.

The only work arounds I can think of are:

1) disable fingerd
2) use tcpwrappers, and have a wrapper program check for the offending pipe and
other shell specials 3) find a third party fingerd that DOESN'T have this wide
open door to root.
