Upgrade to the latest BIND patch level:
Prevents a crash when queried for a record whose RDATA exceeds
65535 bytes.
Prevents a crash when validating caused by using "Bad cache" data
before it has been initialized.
ISC_QUEUE handling for recursive clients was updated to address
a race condition that could cause a memory leak. This rarely
occurred with UDP clients, but could be a significant problem
for a server handling a steady rate of TCP queries.
A condition has been corrected where improper handling of
zero-length RDATA could cause undesirable behavior, including
termination of the named process.

Heavy DNSSEC Validation Load Can Cause a "Bad Cache" Assertion Failure
in BIND9
High numbers of queries with DNSSEC validation enabled can cause an
assertion failure in named, caused by using a "bad cache" data structure
before it has been initialized.
CVE: CVE-2012-3817
Posting date: 24 July, 2012
Upgrade to 9.6-ESV-R7-P1, 9.7.6-P1, 9.8.3-P1, and 9.9.1-P1, the latest
from ISC. These patched versions contain a critical bugfix:
Processing of DNS resource records where the rdata field is zero length
may cause various issues for the servers handling them.
Processing of these records may lead to unexpected outcomes. Recursive
servers may crash or disclose some portion of memory to the client.
Secondary servers may crash on restart after transferring a zone
containing these records. Master servers may corrupt zone data if the
zone option "auto-dnssec" is set to "maintain". Other unexpected
problems that are not listed here may also be encountered.
All BIND users are strongly encouraged to upgrade.
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.
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.

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://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2464https://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".
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
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.

Turns out that the bind.keys.h file is not a new dependency, so my previous
fix was too hasty. Employ a more robust fix that removes the _perl_ dep for
both this file and bind9.xsl.h. The pre-generated versions of these files
are identical to the newly generated ones, which is why this perl issue
never came up previously.
I still have reservations about baking the ISC DLV key into named, but given
that this was already done in 9.7.0+ at least this way we don't violate POLA.
The newly added bind.keys.h file requires perl for its creation,
which is a problem, however what it's doing is baking the ISC
DLV key into named which is not something I think is reasonable
to do by default.
So, instead of adding perl as a build dependency eliminate the
need for the file altogether.
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 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.
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"
