* 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 resolv.conf, 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.
* 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
End of Life
