This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2010:1000 :

Updated bind packages that fix one security issue are now available
for Red Hat Enterprise Linux 4.

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.

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.
