A flaw was found in the DNS64 implementation in BIND when using Response Policy Zones (RPZ). If a remote attacker sent a specially crafted query to a named server that is using RPZ rewrite rules, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not enabled by default. (CVE-2012-5689)

This update also adds the following enhancement :

  - Previously, it was impossible to configure the the     maximum number of responses sent per second to one     client. This allowed remote attackers to conduct traffic     amplification attacks using DNS queries with spoofed     source IP addresses. With this update, it is possible to     use the new 'rate-limit' configuration option in     named.conf and configure the maximum number of queries     which the server responds to. Refer to the BIND     documentation for more details about the 'rate-limit'     option.

After installing the update, the BIND daemon (named) will be restarted automatically.

Updated bind packages that fix one security issue and add one enhancement are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

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. DNS64 is used to automatically generate DNS records so IPv6 based clients can access IPv4 systems through a NAT64 server.

All bind users are advised to upgrade to these updated packages, which contain patches to correct this issue and add this enhancement. After installing the update, the BIND daemon (named) will be restarted automatically.

The remote host is affected by the vulnerability described in GLSA-201401-34 (BIND: Denial of Service)

    Multiple vulnerabilities have been discovered in BIND. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2693-1 advisory.

    Jonathan Foote discovered that Bind incorrectly handled certain TKEY queries. A remote attacker could use     this issue with a specially crafted packet to cause Bind to crash, resulting in a denial of service.
    (CVE-2015-5477)

    Pories Ediansyah discovered that Bind incorrectly handled certain configurations involving DNS64. A remote     attacker could use this issue with a specially crafted query to cause Bind to crash, resulting in a denial     of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-5689)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
