"According to the versions of the bind packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerabilities :

  - In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 ->
    9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND
    9 Supported Preview Edition, An attacker on the network
    path for a TSIG-signed request, or operating the server
    receiving the TSIG-signed request, could send a
    truncated response to that request, triggering an
    assertion failure, causing the server to exit.
    Alternately, an off-path attacker would have to
    correctly guess when a TSIG-signed request was sent,
    along with other characteristics of the packet and
    message, and spoof a truncated response to trigger an
    assertion failure, causing the server to
    exit.(CVE-2020-8622)

  - In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 ->
    9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the
    BIND 9 Supported Preview Edition, An attacker that can
    reach a vulnerable system with a specially crafted
    query packet can trigger a crash. To be vulnerable, the
    system must: * be running BIND that was built with
    '--enable-native-pkcs11' * be signing one or more zones
    with an RSA key * be able to receive queries from a
    possible attacker(CVE-2020-8623)

  - 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)

  - 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)
