Description

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:

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

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

For the old stable distribution (woody) these problems have been fixed in version 0.1.16-2.2.

For the stable distribution (sarge) these problems have been fixed in version 0.2.20-1sarge1.

For the unstable distribution (sid) these problems have been fixed in version 0.2.20-1sarge1.

We recommend that you upgrade your masqmail package.
