The remote host is affected by the vulnerability described in GLSA-201805-08 (VirtualBox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in VirtualBox. Please       review the CVE identifiers referenced below for details.
  Impact :

    An attacker could take control of VirtualBox resulting in the execution       of arbitrary code with the privileges of the process, a Denial of Service       condition, or other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

The version of Oracle VM VirtualBox running on the remote host is 5.1.x prior to 5.1.36 or 5.2.x prior to 5.2.10. It is, therefore, affected by multiple vulnerabilities as noted in the April 2018 Critical Patch Update advisory. Please consult the CVRF details for the applicable CVEs for additional information.

Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for VirtualBox to version 5.1.36 fixes multiple issues :
