Trustix Secure Linux Security Advisory #2003-0044
Package name: bind
Summary: negative cache sec. fix
Date: 2003-11-27
Affected versions: TSL 1.2, 1.5

Package description:
BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses, and a resolver library (routines for applications to use when interfacing with DNS). A DNS server allows clients to name resources or objects and share the information with other network machines. The named DNS server can be used on workstations as a caching name server, but is generally only needed on one machine for an entire network. Note that the configuration files for making BIND act as a simple caching nameserver are included in the caching-nameserver package.Install the bind package if you need a DNS server for your network. If you want bind to act a caching name server, you will also need to install the caching-nameserver package.

Problem description:
According the the bind announcment dated Thu, 27 Nov 2003, the new upstream bind 8.3.7 fixes a security problem:

Security Fix: Negative Cache Poison Fix.

This issue has been addressed in these updates.
