                   Red Hat Security Advisory

Synopsis:          Important: bind security and bug fix update
Advisory ID:       RHSA-2017:1679-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:1679
Issue date:        2017-07-05
CVE Names:         CVE-2017-3142 CVE-2017-3143
=====================================================================

1. Summary:

An update for bind is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - 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.

Security Fix(es):

* A flaw was found in the way BIND handled TSIG authentication for dynamic
updates. A remote attacker able to communicate with an authoritative BIND
server could use this flaw to manipulate the contents of a zone, by forging
a valid TSIG or SIG(0) signature for a dynamic update request.
(CVE-2017-3143)

* A flaw was found in the way BIND handled TSIG authentication of AXFR
requests. A remote attacker, able to communicate with an authoritative BIND
server, could use this flaw to view the entire contents of a zone by
sending a specially constructed request packet. (CVE-2017-3142)

Red Hat would like to thank Internet Systems Consortium for reporting these
issues. Upstream acknowledges Clement Berthaux (Synacktiv) as the original
reporter of these issues.

Bug Fix(es):

* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK)
rollover during October 2017. Maintaining an up-to-date KSK, by adding the
new root zone KSK, is essential for ensuring that validating DNS resolvers
continue to function following the rollover. (BZ#1458234)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

After installing the update, the BIND daemon (named) will be restarted
automatically.
