bind security update

CentOS Errata and Security Advisory CESA-2010:1000

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.

It was discovered that named did not invalidate previously cached SIG
records when adding an NCACHE record for the same entry to the cache. A
remote attacker allowed to send recursive DNS queries to named could use
this flaw to crash named. (CVE-2010-3613)

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