bind97 security update

CentOS Errata and Security Advisory CESA-2012:1266

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 flaw was found in the way BIND handled resource records with a large
RDATA value. A malicious owner of a DNS domain could use this flaw to
create specially-crafted DNS resource records, that would cause a recursive
resolver or secondary server to exit unexpectedly with an assertion
failure. (CVE-2012-4244)

Users of bind97 are advised to upgrade to these updated packages, which
correct this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.
