Package : masqmail
Vulnerability : several
Problem type : local
Debian-specific: no
CVE ID : CAN-2005-2662 CAN-2005-2663

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.

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.
