"According to the versions of the libdb packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
