> Debian-specific: no

> The telnet daemon contained in the netkit-telnet-ssl_0.16.3-1
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 <scut@nb.in-berlin.de>, 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
http://www.securityfocus.com/archive/1/203000 .
> 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-ssl packages to the
