"Jens Steube discovered two vulnerabilities in masqmail, a mailer for
hosts without permanent internet connection. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CAN-2005-2662
    When sending failed mail messages, the address is not
    sanitised, which allows a local attacker to execute
    arbitrary commands as the mail user.

  - CAN-2005-2663

    When opening the log file, masqmail does not relinquish
    privileges, which allows a local attacker to overwrite
    arbitrary files via a symlink attack."
