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.
