"The version of AHV installed on the remote host is prior to 20201105.1161. It is, therefore, affected by a vulnerability
as referenced in the NXSA-AHV-20201105.1161 advisory.

  - 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 (CVE-2020-8625)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
