Debian DSA-247-1 : courier-ssl - missing input sanitizing

high Nessus Plugin ID 15084

Synopsis

The remote Debian host is missing a security-related update.

Description

The developers of courier, an integrated user side mail server, discovered a problem in the PostgreSQL auth module. Not all potentially malicious characters were sanitized before the username was passed to the PostgreSQL engine. An attacker could inject arbitrary SQL commands and queries exploiting this vulnerability. The MySQL auth module is not affected.

Solution

Upgrade the courier-authpostgresql package.

For the stable distribution (woody) this problem has been fixed in version 0.37.3-3.3.

The old stable distribution (potato) does not contain courier packages.
