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

  - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local 
    attacker can exploit this issue, to compromise and takeover the Oracle VM VirtualBox. (CVE-2020-2742, 
    CVE-2020-2758, CVE-2020-2894, CVE-2020-2905, CVE-2020-2908, CVE-2020-2902, CVE-2020-2907, CVE-2020-2911,
    CVE-2020-2913, CVE-2020-2914, CVE-2020-2929, CVE-2020-2958)

  - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local
    attacker can exploit this issue, for unauthorized access to critical data or complete access to all 
    Oracle VM VirtualBox accessible data. (CVE-2020-2741, CVE-2020-2743)

  - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local
    attacker can exploit this issue, for unauthorized read access to a subset of Oracle VM VirtualBox 
    accessible data. (CVE-2020-2748)

   - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local
    attacker can exploit this issue, for unauthorized creation, deletion or modification access to critical 
    data or all Oracle VM VirtualBox accessible data. (CVE-2020-2910)
       
  - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local
    attacker can exploit this issue, for unauthorized ability to cause a partial denial of service 
    (partial DOS) of Oracle VM VirtualBox. (CVE-2020-2909)    
 
 - An unspecified vulnerability exists in the Oracle Virtualization Core component. An authenticated, local
    attacker can exploit this issue, for unauthorized ability to cause a hang or frequently repeatable crash 
    (complete DOS) of Oracle VM VirtualBox. (CVE-2020-2959, CVE-2020-2951)");
