Several problems have been discovered in telnet clients that could be
exploited by malicious daemons the client connects to. The Common
Vulnerabilities and Exposures project identifies the following
problems:
CAN-2005-0468
Gaël Delalleau discovered a buffer overflow in the env_opt_add()
function that allow a remote attacker to execute arbitrary code.
CAN-2005-0469
Gaël Delalleau 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) these problems have been fixed in
version 1.1-8-2.4.
For the testing distribution (sarge) these problems have been fixed in
version 1.2.2-11.2.
For the unstable distribution (sid) these problems have been fixed in
version 1.2.2-11.2.
