  - Vulnerability in the Data Store component of Oracle Berkeley DB. Supported versions that are affected are
    Prior to 6.138, prior to 6.2.38 and prior to 18.1.32. Easily exploitable vulnerability allows low
    privileged attacker having Local Logon privilege with logon to the infrastructure where Data Store
    executes to compromise Data Store. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a partial denial of service (partial DOS) of Data Store. (CVE-2019-2708)

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