Test ID:1.3.6.1.4.1.25623.1.0.871396
Category:Red Hat Local Security Checks
Title:RedHat Update for bind RHSA-2015:1471-01
Summary:The remote host is missing an update for the 'bind'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'bind'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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 found in the way BIND performed DNSSEC validation. An attacker
able to make BIND (functioning as a DNS resolver with DNSSEC validation
enabled) resolve a name in an attacker-controlled domain could cause named
to exit unexpectedly with an assertion failure. (CVE-2015-4620)

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

All bind 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.

Affected Software/OS:
bind on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
