                   Red Hat Security Advisory

Synopsis:          Moderate: bind97 security update
Advisory ID:       RHSA-2016:0074-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-0074.html
Issue date:        2016-01-27
CVE Names:         CVE-2015-8704 
=====================================================================

1. Summary:

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 Moderate 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64

3. Description:

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 processed certain
malformed Address Prefix List (APL) records. A remote, authenticated
attacker could use this flaw to cause named to crash. (CVE-2015-8704)

Red Hat would like to thank ISC for reporting this issue.

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):
