"Updated bind97 packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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."
