"From Red Hat Security Advisory 2010:0975 :

Updated bind packages that fix two security issues are now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
(named); a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is
operating correctly.

It was discovered that named did not invalidate previously cached
RRSIG records when adding an NCACHE record for the same entry to the
cache. A remote attacker allowed to send recursive DNS queries to
named could use this flaw to crash named. (CVE-2010-3613)

It was discovered that, in certain cases, named did not properly
perform DNSSEC validation of an NS RRset for zones in the middle of a
DNSKEY algorithm rollover. This flaw could cause the validator to
incorrectly determine that the zone is insecure and not protected by
DNSSEC. (CVE-2010-3614)

All BIND users are advised to upgrade to these updated packages, which
contain a backported patch to resolve these issues. After installing
the update, the BIND daemon (named) will be restarted automatically.");
