Modified Files: src/libexec/telnetd [netbsd-9]: telnetd.c Log Message: Pull up following revision(s) (requested by dholland in ticket #1508): libexec/telnetd/telnetd.c: revision 1.58 (via patch) telnetd: fix the crash that's been talked about the past couple days. (Move initialization of the slc table earlier so it doesn't get accessed before that happens.) Calling the crash a DoS or security problem is a bit overwrought; it's just a bug.
