the openSUSE-SU-2021:1826-1 advisory.

  - In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and
    9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11
    of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR
    triggering the flaw described above, the named process will terminate due to a failed assertion the next
    time the transferred secondary zone is refreshed. (CVE-2021-25214)

  - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->
    9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND
    9.17 development branch, when a vulnerable version of named receives a query for a record triggering the
    flaw described above, the named process will terminate due to a failed assertion check. The vulnerability
    affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other
    versions of BIND 9. (CVE-2021-25215)
