"According to the versions of the bind packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

  - 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)
