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.
