If a server is configured with a response policy zone (RPZ) that rewrites an answer with local data, and is also configured for DNS64 address mapping, a NULL pointer can be read triggering a server crash. This flaw is disclosed in CVE-2017-3135. [RT #44434]
named could mishandle authority sections with missing RRSIGs, triggering an assertion failure. This flaw is disclosed in CVE-2016-9444. [RT #43632]
named mishandled some responses where covering RRSIG records were returned without the requested data, resulting in an assertion failure. This flaw is disclosed in CVE-2016-9147. [RT #43548]
named incorrectly tried to cache TKEY records which could trigger an assertion failure when there was a class mismatch. This flaw is disclosed in CVE-2016-9131. [RT #43522]
It was possible to trigger assertions when processing responses containing answers of type DNAME. This flaw is disclosed in CVE-2016-8864. [RT #43465]
It was possible to trigger a assertion when rendering a message using a specially crafted request. This flaw is disclosed in CVE-2016-2776. [RT #43139]
Calling getrrsetbyname() with a non
absolute name could trigger an infinite recursion bug in
lwresd or named with
lwres configured if, when combined with
a search list entry from
the resulting name is too long. This flaw is disclosed in
CVE-2016-2775. [RT #42694]
A synthesized CNAME record appearing in a response before the associated DNAME could be cached, when it should not have been. This was a regression introduced while addressing CVE-2016-8864. [RT #44318]
Fixed a crash when calling rndc stats on some Windows builds: some Visual Studio compilers generate code that crashes when the "%z" printf() format specifier is used. [RT #42380]
ECS clients with the option set to 0.0.0.0/0/0 or ::/0/0 were incorrectly getting a FORMERR response.
Windows installs were failing due to triggering UAC without the installation binary being signed.
A race condition in rbt/rbtdb was leading to INSISTs being triggered.
The end of life for BIND 9.10 is yet to be determined but will not be before BIND 9.12.0 has been released for 6 months. https://www.isc.org/downloads/software-support-policy/
