Vulnerability Assessment Details

[DSA848] DSA-848-1 masqmail

Vulnerability Assessment Summary
DSA-848-1 masqmail

Detailed Explanation for this Vulnerability Assessment

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 permits a local attacker to execute arbitrary commands as the
mail user.
When opening the log file, masqmail does not relinquish
rights, which permits 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.
