Debian DSA-363-1 : postfix - denial of service, bounce-scanning

medium Nessus Plugin ID 15200

Synopsis

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

Description

The postfix mail transport agent in Debian 3.0 contains two vulnerabilities :

 - CAN-2003-0468: Postfix would allow an attacker to bounce-scan private networks or use the daemon as a DDoS tool by forcing the daemon to connect to an arbitrary service at an arbitrary IP address and either receiving a bounce message or observing queue operations to infer the status of the delivery attempt.
 - CAN-2003-0540: a malformed envelope address can 1) cause the queue manager to lock up until an entry is removed from the queue and 2) lock up the smtp listener leading to a denial of service.

Solution

For the current stable distribution (woody) these problems have been fixed in version 1.1.11-0.woody3.


We recommend that you update your postfix package.
