Updated bind packages that fix a security issue and a bug are now available
for Red Hat Enterprise Linux 5.
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 a remote
attacker to cause a denial of service. (CVE-2007-0494)
A use-after-free flaw was found in BIND. On servers that have recursion
enabled, this could allow a remote attacker to cause a denial of service.
Users of BIND are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
