Package        : netkit-telnet-ssl
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-0469

iDEFENSE researchers discovered a buffer overflow in the handling of
the LINEMODE suboptions in telnet clients.  This can lead to the
execution of arbitrary code when connected to a malicious server.

For the stable distribution (woody) this problem has been fixed in
version 0.17.17+0.1-2woody4.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your telnet-ssl package.
