Red Hat Security Advisory
Synopsis: Moderate: bind security update
Advisory ID: RHSA-2010:0062-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0062.html
Issue date: 2010-01-20
CVE Names: CVE-2010-0097 CVE-2010-0290
=====================================================================
1. Summary:
Updated bind packages that fix two security issues 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.
2. Relevant releases/architectures:
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
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.
A flaw was found in the BIND DNSSEC NSEC/NSEC3 validation code. If BIND was
running as a DNSSEC-validating resolver, it could incorrectly cache
NXDOMAIN responses, as if they were valid, for records proven by NSEC or
NSEC3 to exist. A remote attacker could use this flaw to cause a BIND
server to return the bogus, cached NXDOMAIN responses for valid records and
prevent users from retrieving those records (denial of service).
(CVE-2010-0097)
The original fix for CVE-2009-4022 was found to be incomplete. BIND was
incorrectly caching certain responses without performing proper DNSSEC
validation. CNAME and DNAME records could be cached, without proper DNSSEC
validation, when received from processing recursive client queries that
requested DNSSEC records but indicated that checking should be disabled. A
remote attacker could use this flaw to bypass the DNSSEC validation check
and perform a cache poisoning attack if the target BIND server was
receiving such client queries. (CVE-2010-0290)
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 that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
554851 - CVE-2010-0097 BIND DNSSEC NSEC/NSEC3 validation code could cause bogus NXDOMAIN responses
557121 - CVE-2010-0290 BIND upstream fix for CVE-2009-4022 is incomplete
