Bugtraq: Re: in.fingerd vulnerability

[brian () ASL-LABS BC CA (Brian Hampson)]

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.

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