Debian Security Advisory DSA 363-1 [email protected]
http://www.debian.org/security/ Matt Zimmerman
August 3rd, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package : postfix
Vulnerability : denial of service, bounce-scanning
Problem-Type : remote
Debian-specific: no
CVE Ids : CAN-2003-0468, CAN-2003-0540

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

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

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you update your postfix package.
