bind97 security update

CentOS Errata and Security Advisory CESA-2013:1115

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 BIND. A remote attacker could use
this flaw to send a specially-crafted DNS query to named that, when
processed, would cause named to crash when rejecting the malformed query.
(CVE-2013-4854)

All bind97 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
update, the BIND daemon (named) will be restarted automatically.
