Hi,

I reported segfaults of telnetd 0.17 to RedHat on July 30, they
posted some fix (July 31), but haven't released advisory yet. Please
check following URLs:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=50335
ftp://people.redhat.com/harald/telnet-0.17-16.src.rpm


Patch from RedHat in telnet-0.17-16 is bigger than one posted here, but I
can't check whether it is enough (at least telnetd won't segfault).
