Red Hat Security Advisory

 

Synopsis: Important: bind97 security update

Advisory ID: RHSA-2011:1459-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1459.html

Issue date: 2011-11-17

CVE Names: CVE-2011-4313

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

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, 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 flaw was discovered in the way BIND handled certain DNS queries, which

caused it to cache an invalid record. A remote attacker could use this

flaw to send repeated queries for this invalid record, causing the

resolvers to exit unexpectedly due to a failed assertion. (CVE-2011-4313)

 

Users of bind97 are advised to upgrade to these updated packages, which

resolve 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.

 

This update is available via the Red Hat Network. Details on how to

use the Red Hat Network to apply this update are available at

https://access.redhat.com/kb/docs/DOC-11259

 

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

 

754398 - CVE-2011-4313 bind: Remote denial of service against recursive servers via logging negative cache entry
