bind, caching security update

CentOS Errata and Security Advisory CESA-2014:1984

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 followed DNS
delegations. A remote attacker could use a specially crafted zone
containing a large number of referrals which, when looked up and processed,
would cause named to use excessive amounts of memory or crash.
(CVE-2014-8500)

All bind 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.
