Red Hat Security Advisory

 

Synopsis: Important: bind97 security update

Advisory ID: RHSA-2015:2658-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2658.html

Issue date: 2015-12-16

CVE Names: CVE-2015-8000

=====================================================================

 

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 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.

 

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

records with malformed class attributes. A remote attacker could use this

flaw to send a query to request a cached record with a malformed class

attribute that would cause named functioning as an authoritative or

recursive server to crash. (CVE-2015-8000)

 

Note: This issue affects authoritative servers as well as recursive

servers, however authoritative servers are at limited risk if they perform

authentication when making recursive queries to resolve addresses for

servers listed in NS RRSETs.

 

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.

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

 

1291176 - CVE-2015-8000 bind: responses with a malformed class attribute can trigger an assertion failure in db.c
