safe_finger command protects against nasty stuff from
finger servers. Use this program for automatic reverse
finger probes from the tcp_wrapper (tcpd) , not the
raw finger command. The safe_finger command makes
sure that the finger client is not run with root privileges.
It also runs the finger client with a defined PATH
environment. safe_finger will also protect you from
problems caused by the output of some finger servers. The
problem: some programs may react to stuff in the first
column. Other programs may get upset by thrash anywhere on a
line. File systems may fill up as the finger server keeps
sending data. Text editors may bomb out on extremely long
lines. The finger server may take forever because it is
somehow wedged. safe_finger takes care of all this
