Notes for BIND 9.19.1
---------------------
Security Fixes
~~~~~~~~~~~~~~
- Previously, TLS socket objects could be destroyed prematurely, which
triggered assertion failures in :iscman:`named` instances serving
DNS-over-HTTPS (DoH) clients. This has been fixed.
ISC would like to thank Thomas Amgarten from arcade solutions ag for
bringing this vulnerability to our attention. (CVE-2022-1183)
:gl:`#3216`
New Features
~~~~~~~~~~~~
- Catalog Zones schema version 2, as described in the
"DNS Catalog Zones" IETF draft version 5 document, is now supported by
:iscman:`named`. All of the previously supported BIND-specific catalog
zone custom properties (``primaries``, ``allow-query``, and
``allow-transfer``), as well as the new Change of Ownership (``coo``)
property, are now implemented. Schema version 1 is still supported,
with some additional validation rules applied from schema version 2:
for example, the ``version`` property is mandatory, and a member zone
PTR RRset must not contain more than one record. In the event of a
validation error, a corresponding error message is logged to help with
diagnosing the problem. :gl:`#3221` :gl:`#3222` :gl:`#3223`
:gl:`#3224` :gl:`#3225`
- Support DNS Extended Errors (:rfc:`8914`) ``Stale Answer`` and
``Stale NXDOMAIN Answer`` when stale answers are returned from cache.
:gl:`#2267`
- The Object Identifier (OID) embedded at the start of a PRIVATEOID
public key in a KEY, DNSKEY, CDNSKEY, or RKEY resource records is now
checked to ensure that it is valid when reading from zone files or
receiving data on the wire. The Object Identifier is now printed when
the ``dig +rrcomments`` option is used. Similarly, the name embedded
at the start of a PRIVATEDNS public key is also checked for validity.
:gl:`#3234`
- The Object Identifier (OID) embedded at the start of a PRIVATEOID
signature in a SIG, or RRSIG resource records is now checked to
ensure that it is valid when reading from zone files or receiving
data on the wire. Similarly, the name embedded at the start of
a PRIVATEDNS public key is also checked for validity. :gl:`#3296`
Bug Fixes
~~~~~~~~~
- Previously, CDS and CDNSKEY DELETE records were removed from the zone
when configured with the ``auto-dnssec maintain;`` option. This has
been fixed. :gl:`#2931`
