Moderate: bind security update

Updated bind packages that fix a security issue and a bug are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols.

A flaw was found in the way BIND processed certain DNS query responses. On
servers that had enabled DNSSEC validation, this could allow an remote
attacker to cause a denial of service. (CVE-2007-0494)

For users of Red Hat Enterprise Linux 3, the previous BIND update caused an
incompatible change to the default configuration that resulted in rndc not
sharing the key with the named daemon. This update corrects this bug and
restores the behavior prior to that update.

Updating the bind package in Red Hat Enterprise Linux 3 could result in
nonfunctional configuration in case the bind-libs package was not updated.
This update corrects this bug by adding the correct dependency on bind-libs.

Users of BIND are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
