Upgrade to BIND versions 9.9.1, 9.8.3, 9.7.6, and 9.6-ESV-R7,
the latest from ISC. These versions all contain the following:

Feature Change

*  BIND now recognizes the TLSA resource record type, created to
   support IETF DANE (DNS-based Authentication of Named Entities)
   [RT #28989]

Bug Fix

*  The locking strategy around the handling of iterative queries
   has been tuned to reduce unnecessary contention in a multi-
   threaded environment.

Each version also contains other critical bug fixes.

All BIND users are encouraged to upgrade to these latest versions.

Update to version 9.7.5, the latest from ISC, which contains numerous bug fixes.

For the port, switch to using the PORTDOCS macro.

Feature safe:   yes

Upgrade to the latest security patch releases to address the
following DDOS bug:

Recursive name servers are failing with an assertion:
INSIST(! dns_rdataset_isassociated(sigrdataset))

At this time it is not thought that authoritative-only servers
are affected, but information about this bug is evolving rapidly.

Because it may be possible to trigger this bug even on networks
that do not allow untrusted users to access the recursive name
servers (perhaps via specially crafted e-mail messages, and/or
malicious web sites) it is recommended that ALL operators of
recursive name servers upgrade immediately.

For more information see:
https://www.isc.org/software/bind/advisories/cve-2011-tbd
which will be updated as more information becomes available.

Update to version 9.7.4 which contains various bug fixes and improvements:

ftp://ftp.isc.org/isc/bind9/9.7.4/RELEASE-NOTES-BIND-9.7.4.html

Update to versions 9.7.3-P3, and 9.6-ESV-R4-P3.

ALL BIND USERS ARE ENCOURAGED TO UPGRADE IMMEDIATELY

This update addresses the following vulnerability:

CVE-2011-2464
=============
Severity:       High
Exploitable:    Remotely

Description:

A defect in the affected BIND 9 versions allows an attacker to remotely
cause the "named" process to exit using a specially crafted packet. This
defect affects both recursive and authoritative servers. The code location
of the defect makes it impossible to protect BIND using ACLs configured
within named.conf or by disabling any features at compile-time or run-time.

https://www.isc.org/software/bind/advisories/cve-2011-2464

Upgrade to 9.6-ESV-R4-P1 and 9.7.3-P1, which address the following issues:

1. Very large RRSIG RRsets included in a negative cache can trigger
an assertion failure that will crash named (BIND 9 DNS) due to an
off-by-one error in a buffer size check.

This bug affects all resolving name servers, whether DNSSEC validation
is enabled or not, on all BIND versions prior to today. There is a
possibility of malicious exploitation of this bug by remote users.

2. Named could fail to validate zones listed in a DLV that validated
insecure without using DLV and had DS records in the parent zone.

Add a patch provided by ru@ and confirmed by ISC to fix a crash at
shutdown time when a SIG(0) key is being used.

Update to 9.7.3, the latest from ISC:

 * Zones may be dynamically added and removed with the "rndc addzone"
   and "rndc delzone" commands. These dynamically added zones are
   written to a per-view configuration file. Do not rely on the
   configuration file name nor contents as this will change in a
   future release. This is an experimental feature at this time.
 * A new command "rndc secroots" was added to dump a combined summary
   of the currently managed keys combined with statically configured
   trust anchors.
 * Added support to load new keys into managed zones without signing
   immediately with "rndc loadkeys". Added support to link keys with
   "dnssec-keygen -S" and "dnssec-settime -S".

Update to version 9.7.2-P3, the latest from ISC, which addresses
the following security vulnerabilities.

For more information regarding these issues please see:
http://www.isc.org/announcement/guidance-regarding-dec-1st-2010-security-advisories

1. Cache incorrectly allows ncache and rrsig for the same type

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-3613

   Affects resolver operators whose servers are open to potential
   attackers. Triggering the bug will cause the server to crash.

   This bug applies even if you do not have DNSSEC enabled.

Convert this to a master port for ../bind-tools

Remove CONFLICTS for the now-removed BIND 9.3

Remove OPTION for threads on < RELENG_7

Remove MD5 from distinfo

Update to 9.7.2-P2, the latest version from ISC

Updgrade to version 9.7.1-P2 which addresses a DNSSEC-related bug.

If a query is made explicitly for a record of type 'RRSIG' to a validating
recursive server running BIND 9.7.1 or 9.7.1-P1, and the server has one or
more trust anchors configured statically and/or via DLV, then if the answer
is not already in cache, the server enters a loop which repeatedly generates
queries for RRSIGs to the authoritative servers for the zone containing the
queried name.

CVE:    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0213
CERT:   http://www.kb.cert.org/vuls/id/211905

Versions affected:      9.7.1, 9.7.1-P1
Severity:               High
Exploitable:            remotely

http://www.isc.org/software/bind/advisories/cve-2010-0213

Upgrade to version 9.7.1-P1. The patch addresses 2 areas in the resolver
code where the 9.7.x series tightened its adherence to the DNS protocol
as written, vs. the 9.6.x series which was more liberal in what it accepted.

Specifically:
1. Restore processing of certain forms of negative responses that do
   not contain all of the required elements to avoid aggressive
   re-querying of authority servers.
2. Accept answers from authority servers without the AA bit set
   if they meet the other requirements of an answer packet.

Update to version 9.7.1, the latest from ISC.

This version has numerous minor bug fixes, please refer to the
CHANGES file for details. Many (but not all) of the fixes are
DNSSEC-related, and all users who are doing DNSSEC validation
are encouraged to upgrade to this version.

Update to the latest patch set from ISC, which addresses the following:

   Named could return SERVFAIL for negative responses
   from unsigned zones.

Update to the latest patchfix releases to deal with the problems
related to the handling of broken DNSSEC trust chains.

This fix is only necessary for those who have DNSSEC validation
enabled and configure trust anchors from third parties, either
manually, or through a system like DLV.

Update to the release version of BIND 9.7.0, and remove the -devel
suffix as a result.

Feature safe:   yes

Update to 9.7.0rc2 which has numerous bug fixes, especially
for DNSSEC.

Add BIND 9.7.0rc1 with a -devel suffix for now so that people can
start testing it sooner rather than later. When the final version
is released the -devel will be removed.

Some of the new features of BIND 9.7.x are:

        - Fully automatic signing of zones by "named"
        - Simplified configuration of DNSSEC Lookaside Validation (DLV)
        - Simplified configuration of Dynamic DNS, using the "ddns-confgen"
          command line tool or the "local" update-policy option
        - New named option "attach-cache" that allows multiple views to
          share a single cache
        - DNS rebinding attack prevention
        - New default values for dnssec-keygen parameters
        - Support for RFC 5011 automated trust anchor maintenance
          (see README.rfc5011 for additional details)
        - Smart signing: simplified tools for zone signing and key
          maintenance
        - Improved PKCS#11 support
