    value:
"'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)
