Synopsis:          Remote vulnerabilities in BIND 4 and 8
Issue date:        2002-11-12
CVE Names:         CAN-2002-1219 CAN-2002-1220 CAN-2002-1221

1. Problem description:

BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols.  Three remotely exploitable
vulnerabilities were disclosed by ISC on 12 November 2002 that affect
various versions of BIND 4 and 8.

Versions of Red Hat Linux since 7.1, and Red Hat Linux Advanced Server
shipped with BIND 9 are are therefore not vulnerable to these issues.

Older releases (6.2, 7.0) of Red Hat Linux shipped with versions of BIND
which are vulnerable to these issues, however a Red Hat security errata in
July 2002 upgraded all our supported distributions to BIND 9.2.1 which is
not vulnerable to these issues.

2. Solution:

All users who have BIND installed should ensure that they are already
running version 9 of BIND and preferably upgrade to the lastest errata
packages listed below.  To check if BIND is installed and find the version
number use the command "rpm -qi bind".
