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.

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.

An uninitialized data structure use flaw was found in BIND when DNSSEC
validation was enabled. A remote attacker able to send a large number
of queries to a DNSSEC validating BIND resolver could use this flaw to
cause it to exit unexpectedly with an assertion failure.
(CVE-2012-3817)

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.
