"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2021:0025 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-6465:
    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-2019-6471:
    A race condition which may occur when discarding malformed packets can result in BIND exiting due to a
    REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1,
    9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND
    9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.

    CVE-2020-8617:
    Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an
    inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the
    server. Since BIND, by default, configures a local session key even on servers whose configuration does
    not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating
    from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately
    exits. Prior to the introduction of the check the server would continue operating in an inconsistent
    state, with potentially harmful results.

    CVE-2020-8622:
    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-2020-8623:
    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-2020-8624:
    In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also
    affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An
    attacker who has been granted privileges to change a specific subset of the zone's content could abuse
    these unintended additional privileges to update other contents of the zone.

    CVE-2020-8625:
    BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG
    features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,
    but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or
    tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-
    TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server
    environments that combine BIND servers with Active Directory domain controllers. The most likely outcome
    of a successful exploitation of the vulnerability is a crash of the named process. However, remote code
    execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,
    and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch
