-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 198-1 security@debian.org http://www.debian.org/security/ Martin Schulze November 18th, 2002 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : nullmailer Vulnerability : denial of service Problem-type : local Debian-specific: no A problem has been discovered in nullmailer, a simple relay-only mail transport agent for hosts that relay mail to a fixed set of smart relays. When a mail is to be delivered locally to a user that doesn't exist, nullmailer tries to deliver it, discovers a user unknown error and stops delivering. Unfortunately, it stops delivering entirely, not only this mail. Hence, it's very easy to craft a denial of service. This problem has been fixed in version 1.00RC5-16.1woody2 for the current stable distribution (woody) and in version 1.00RC5-17 for the unstable distribution (sid). The old stable distribution (potato) does not contain a nullmailer package. We recommend that you upgrade your nullmailer package. 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.
