exploited by malicious daemons the client connects to. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - 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."
