Package : netkit-telnet
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 0.17-18woody3.

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

We recommend that you upgrade your telnet package.
