### Old Ubuntu Delta ###

bind9 (1:9.16.15-1ubuntu1) impish; urgency=medium

  * Merge with Debian unstable. Remaining changes:
    - Don't build dnstap as it depends on universe packages:
      + d/control: drop build-depends on libfstrm-dev, libprotobuf-c-dev and
        protobuf-c-compiler (universe packages)
      + d/dnsutils.install: don't install dnstap
      + d/libdns1104.symbols: don't include dnstap symbols
      + d/rules: don't build dnstap nor install dnstap.proto
    - Add back apport:
      + d/bind9.apport: add back old bind9 apport hook, but without calling
        attach_conffiles() since that is already done by apport itself, with
        confirmation from the user.
      + d/control, d/rules: buil-depends on dh-apport and use it
    - d/NEWS: mention some of the bigger changes in 9.16.0 packaging
    - d/bind9.named.service: use systemd Type=forking to signal daemon init.
      This fixes a regression of #900788 where services whose startup depend
      on name resolutions may fail due to bind9 not being ready (LP #1899902).
  * Drop changes:
    - d/t/simpletest: drop the internetsociety.org test as it requires
      network egress access that is not available in the Ubuntu autopkgtest
      farm.
      [Fixed in 1:9.16.11-3]
    - SECURITY UPDATE: off-by-one bug in ISC SPNEGO implementation
      + debian/patches/CVE-2020-8625.patch: properly calculate length in
        lib/dns/spnego.c.
      + CVE-2020-8625
      [Fixed in 1:9.16.12-1]
    - SECURITY UPDATE: DoS via broken inbound incremental zone update (IXFR)
      + debian/patches/CVE-2021-25214.patch: immediately reject the entire
        transfer for certain RR in lib/dns/xfrin.c.
      + CVE-2021-25214
      [Fixed in 1:9.16.15-1]
    - SECURITY UPDATE: assert via answering certain queries for DNAME records
      + debian/patches/CVE-2021-25215.patch: fix assert checks in
        lib/ns/query.c.
      + CVE-2021-25215
      [Fixed in 1:9.16.15-1]
    - SECURITY UPDATE: overflow in BIND's GSSAPI security policy negotiation
      + debian/rules: build with --disable-isc-spnego to disable internal
        SPNEGO and use the one from the kerberos libraries.
