This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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

Red Hat Product Security 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 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 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.
