Red Hat Security Advisory

 

Synopsis: Important: bind97 security update

Advisory ID: RHSA-2016:0458-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0458.html

Issue date: 2016-03-16

CVE Names: CVE-2016-1285 CVE-2016-1286

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

 

1. Summary:

 

Updated bind97 packages that fix two security issues are now available for

Red Hat Enterprise Linux 5.

 

Red Hat Product Security 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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, 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 denial of service flaw was found in the way BIND parsed signature records

for DNAME records. By sending a specially crafted query, a remote attacker

could use this flaw to cause named to crash. (CVE-2016-1286)

 

A denial of service flaw was found in the way BIND processed certain

control channel input. A remote attacker able to send a malformed packet to

the control channel could use this flaw to cause named to crash.

(CVE-2016-1285)

 

Red Hat would like to thank ISC for reporting these issues.

 

All bind97 users are advised to upgrade to these updated packages, which

contain backported patches to correct 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.
