Synopsis: Important: bind97 security update

Advisory ID: RHSA-2017:0064-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0064.html

Issue date: 2017-01-16

CVE Names: CVE-2016-9147

=====================================================================

 

1. Summary:

 

An update for bind97 is now available for Red Hat Enterprise Linux 5.

 

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 (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop Workstation (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.

 

Security Fix(es):

 

* A denial of service flaw was found in the way BIND handled a query

response containing inconsistent DNSSEC information. A remote attacker

could use this flaw to make named exit unexpectedly with an assertion

failure via a specially crafted DNS response. (CVE-2016-9147)

 

Red Hat would like to thank ISC for reporting this issue.

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

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

automatically.
