The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2021-1675 advisory.

  • 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. CVSS 3.0 Base Score 3.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). (CVE-2019-2708)

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