CAN-2005-0468

Gael Delalleau discovered a buffer overflow in the env_opt_add() function that allow a remote attacker to execute arbitrary code.

CAN-2005-0469

Gael 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.

We recommend that you upgrade your krb4 packages.");
