This isn't the only problem with telnetd. If you aren't running the
telnetd from NetKit-B-0.08 (which blocks almost all environment
variables) you are asking for trouble.

(Be advised, btw, that if you install that NetKit, you may not want to
install its version of telnet. There have been some [non-security]
bugs reported; I'm intending to get a fixed version out as soon as I
can but I've been extremely busy.)
