ISC reports:

We have today posted updated versions of 9.9.6 and 9.10.1 to address a significant security vulnerability in DNS resolution. The flaw was discovered by Florian Maury of ANSSI, and applies to any recursive resolver that does not support a limit on the number of recursions. [CERTFR-2014-AVI-512], [USCERT VU#264212]

A flaw in delegation handling could be exploited to put named into an infinite loop, in which each lookup of a name server triggered additional lookups of more name servers. This has been addressed by placing limits on the number of levels of recursion named will allow (default 7), and on the number of queries that it will send before terminating a recursive query (default 50). The recursion depth limit is configured via the max-recursion-depth option, and the query limit via the max-recursion-queries option. For more information, see the security advisory at https://kb.isc.org/article/AA-01216/. [CVE-2014-8500] [RT #37580]

In addition, we have also corrected a potential security vulnerability in the GeoIP feature in the 9.10.1 release only. For more information on this issue, see the security advisory at https://kb.isc.org/article/AA-01217. [CVE-2014-8680]

ISC reports:

BIND 9 nameservers using the DNS64 IPv6 transition mechanism are vulnerable to a software defect that allows a crafted query to crash the server with a REQUIRE assertion failure. Remote exploitation of this defect can be achieved without extensive effort, resulting in a denial-of-service (DoS) vector against affected servers.

ISC reports:

Because of a defect in handling queries for NSEC3-signed zones, BIND can crash with an "INSIST" failure in name.c when processing queries possessing certain properties. By exploiting this defect an attacker deliberately constructing a query with the right properties could achieve denial of service against an authoritative nameserver serving NSEC3-signed zones.

ISC reports:

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.

ISC reports:

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.

BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries could be used before it was fully initialized, triggering an assertion failure.

This bug cannot be encountered unless your server is doing DNSSEC validation.
