The version of Samba running on the remote host is 4.9.x < 4.9.9 or 4.10.0 prior to 4.10.5. It is, therefore, potentially affected by a denial of service vulnerability in the AD DC DNS management server (dnsserver) RPC server process. 

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

  - A flaw was found in the way samba implemented an RPC     endpoint emulating the Windows registry service API. An     unprivileged attacker could use this flaw to create a     new registry hive file anywhere they have unix     permissions which could lead to creation of a new file     in the Samba share.(CVE-2019-3880)
