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 the libdns library. A remote attacker
could use this flaw to send a specially-crafted DNS query to named that,
when processed, would cause named to use an excessive amount of memory, or
possibly crash. (CVE-2013-2266)

Note: This update disables the syntax checking of NAPTR (Naming Authority
Pointer) resource records.

All bind97 users are advised to upgrade to these updated packages, which
contain a patch to correct this issue. After installing the update, the
BIND daemon (named) will be restarted automatically.
