Synopsis:          Important: bind security update
Advisory ID:       RHSA-2010:0975-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2010:0975.html

====================================================================
1. Summary:

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.

3. Description:

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.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at

5. Bugs fixed (http://bugzilla.redhat.com/):

658974 - CVE-2010-3613 bind: failure to clear existing RRSIG records when a NO DATA is negatively cached could DoS named
658977 - CVE-2010-3614 bind: key algorithm rollover may mark secure answers as insecure
