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 processed a
response to an ANY query. A remote attacker could use this flaw to
make named exit unexpectedly with an assertion failure via a specially
crafted DNS response. (CVE-2016-9131)

* 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)

* A denial of service flaw was found in the way BIND handled an
unusually-formed DS record response. A remote attacker could use this
flaw to make named exit unexpectedly with an assertion failure via a
