As distributed, SunOS 4.0 has the same bug.  However, since SunOS 4.0 uses
a 4.3BSD-style inetd.conf, you can easily fix it.

     Just edit /etc/inetd.conf, and change the line that says:

finger	stream  tcp	nowait  root	/usr/etc/in.fingerd	in.fingerd

     to say

finger	stream  tcp	nowait  nobody  /usr/etc/in.fingerd	in.fingerd

This will cause in.fingerd to run as nobody instead of root.  Make sure
you've got a nobody in your passwd file.  The fix mentioned above (making
in.fingerd owned, grouped, setuid and setgid to nobody/nogroup) also
works.
