Debian Security Advisory DSA-070-1                             Robert van der Meulen
August 10, 2001

Package        : netkit-telnet
Problem type   : remote exploit
Debian-specific: no

The telnet daemon contained in the netkit-telnet_0.16-4potato1 package in
the 'stable' (potato) distribution of Debian GNU/Linux is vulnerable to an
exploitable overflow in its output handling.
The original bug was found by <>, and announced to
bugtraq on Jul 18 2001. At that time, netkit-telnet versions after 0.14 were
not believed to be vulnerable.
On Aug 10 2001, zen-parse posted an advisory based on the same problem, for
all netkit-telnet versions below 0.17.
More details can be found on .
As Debian uses the 'telnetd' user to run in.telnetd, this is not a remote
root compromise on Debian systems; the 'telnetd' user can be compromised.

We strongly advise you update your netkit-telnet packages to the versions
listed below.
