"From Red Hat Security Advisory 2016:1944 :

An update for bind is now available for Red Hat Enterprise Linux 5,
Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7.

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.

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 constructed a
response to a query that met certain criteria. A remote attacker could
use this flaw to make named exit unexpectedly with an assertion
failure via a specially crafted DNS request packet. (CVE-2016-2776)

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