RHEL 6 : bind (RHSA-2016:0601)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for bind is now available for Red Hat Enterprise Linux 6.2
Advanced Update Support.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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.

Security Fix(es) :

* A denial of service flaw was found in the way BIND parsed signature
records for DNAME records. By sending a specially crafted query, a
remote attacker could use this flaw to cause named to crash.
(CVE-2016-1286)

* A denial of service flaw was found in the way BIND processed certain
control channel input. A remote attacker able to send a malformed
packet to the control channel could use this flaw to cause named to
crash. (CVE-2016-1285)

Red Hat would like to thank ISC for reporting these issues.
