You can download the "patch" for in.telnetsnoopd from sunsite.
you will need the old source for telnetsnoopd too..

I'm not sure if this has been discussed or not, but in.telnetsnoopd is
exploitable on my Linux Slackware 2.0.27 system.
As most know, the standard in.telnetd was patched against the 'libroot'
exploit that made use of the "LD_PRELOAD" command in telnet. The patch (if
I remember correctly) blocked environment variables longer than xxxx from
being passed as an argument as "libroot" was. Unfortunately, it seems
someone overlooked telnetsnoop, as this is still exploitable.
Edit your inetd.conf to reenable standard telnet, rather than snoop telnet.
Snooping is bad manners anyways =).
