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.
