===================================================================== 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.
