"BIND 9.11.0-P5 addresses the security issues described in CVE-2017-3136,
CVE-2017-3137, and CVE-2017-3138, and updates the built-in trusted keys for the root zone.

Security Fixes

rndc "" could trigger an assertion failure in named. This flaw is disclosed in
(CVE-2017-3138). [RT #44924]

Some chaining (i.e., type CNAME or DNAME) responses to upstream queries could
trigger assertion failures. This flaw is disclosed in CVE-2017-3137. [RT #44734]

dns64 with break-dnssec yes; can result in an assertion failure. This flaw is
disclosed in CVE-2017-3136. [RT #44653]

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]

A coding error in the nxdomain-redirect feature could lead to an assertion failure if
the redirection namespace was served from a local authoritative data source such as a
local zone or a DLZ instead of via recursive lookup. This flaw is disclosed in
CVE-2016-9778. [RT #43837]

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]

Bug Fixes

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]

Best,
