bind97 security update

CentOS Errata and Security Advisory CESA-2016:0458

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.
