Debian alert: New postfix packages fix remote denial of service, bounce scanning
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 363-1 security@debian.org 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. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
