Vulnerable versions: GNU InetUtils since version 1.9.3 up to and including version 2.7.

Looking at Debian, this gets even more hilarious... Their
changelog for inetutils has:

inetutils (2:1.9.4-7) unstable; urgency=medium
[..]
* Take several patches from upstream git master:

  - 0028-telnetd-Scrub-USER-from-environment.patch

I think this is unrelated.

The bug is reproducible with inetutils-telnetd 2:1.9.4-7 too.
