Red Hat Security Advisory

 

Synopsis: Important: bind security update

Advisory ID: RHSA-2016:0601-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0601.html

Issue date: 2016-04-06

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

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

 

1. Summary:

 

An update for bind is now available for Red Hat Enterprise Linux 6.2

Advanced Update Support.

 

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 Server AUS (v. 6.2) - x86_64

Red Hat Enterprise Linux Server Optional AUS (v. 6.2) - 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 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.

 

4. Solution:

 

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

described in this advisory, refer to:
