  - Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones
    are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and
    versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13
    development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for
    vulnerability to CVE-2019-6465. (CVE-2019-6465)

  - managed-keys is a feature which allows a BIND resolver to automatically maintain the keys used by trust
    anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys
    feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if,
    during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm.
    Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions
    9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13
    development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for
    vulnerability to CVE-2018-5745. (CVE-2018-5745)
