Actually, it might. I ran strace on the telnetd process, which should
mostly proxy data between a child process (login, at that point) and the
socket. It isn't. I just looked at the spec in git; there don't appear
to be any changes since F17. Any bug that's new to F18 would have to be
external to telnetd's source.
As long as you're concerned with compatibility over security, have you
considered using rsh instead? As much a problem as telnet is where
security is involved, the biggest one you face now is finding anyone
motivated to fix it. telnetd is more complicated than you think,
probably. It's not a simply proxy to a local process/tty. The client
and server actually exchange a bunch of options in a binary handshake.
Finding the bug could take a while if you can't get the author's
attention, and I don't think that code has been maintained for a long time.
