BIND 9.11.2-P1 addresses the security issue described in CVE-2017-3145.
New DNSSEC Root Key
- This release includes an updated version of the bind.keys file
containing the new root key. This file can also be downloaded from
https://www.isc.org/bind-keys
License Change
- With the release of BIND 9.11.0, ISC changed to the open source license
for BIND from the ISC license to the Mozilla Public License (MPL 2.0).
Windows XP No Longer Supported
Security Fixes
* Addresses could be referenced after being freed during resolver
processing, causing an assertion failure. The chances of this
happening were remote, but the introduction of a delay in
resolution increased them. (The delay will be addressed in an
upcoming maintenance release.) This bug is disclosed in
CVE-2017-3145. [RT #46839]
* An error in TSIG handling could permit unauthorized zone transfers
or zone updates. These flaws are disclosed in CVE-2017-3142 and
CVE-2017-3143. [RT #45383]
* The BIND installer on Windows used an unquoted service path, which
can enable privilege escalation. This flaw is disclosed in
CVE-2017-3141. [RT #45229]
* With certain RPZ configurations, a response with TTL 0 could cause
named to go into an infinite query loop. This flaw is disclosed in
CVE-2017-3140. [RT #45181]
Feature Changes
* dig +ednsopt now accepts the names for EDNS options in addition to
numeric values. For example, an EDNS Client-Subnet option could be
sent using dig +ednsopt=ecs:.... Thanks to John Worley of Secure64
for the contribution. [RT #44461]
* Threads in named are now set to human-readable names to assist
debugging on operating systems that support that. Threads will have
names such as "isc-timer", "isc-sockmgr", "isc-worker0001", and so
on. This will affect the reporting of subsidiary thread names in ps
and top, but not the main thread. [RT #43234]
* DiG now warns about .local queries which are reserved for Multicast
DNS. [RT #44783]
Bug Fixes
* Fixed a bug that was introduced in an earlier development release
which caused multi-packet AXFR and IXFR messages to fail validation
if not all packets contained TSIG records; this caused
interoperability problems with some other DNS implementations. [RT
#45509]
* Reloading or reconfiguring named could fail on some platforms when
LMDB was in use. [RT #45203]
* Due to some incorrectly deleted code, when BIND was built with
LMDB, zones that were deleted via rndc delzone were removed from
the running server but were not removed from the new zone database,
so that deletion did not persist after a server restart. This has
been corrected. [RT #45185]
* Semicolons are no longer escaped when printing CAA and URI records.
This may break applications that depend on the presence of the
backslash before the semicolon. [RT #45216]
* AD could be set on truncated answer with no records present in the
answer and authority sections. [RT #45140]
