Update advisory:

  - 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-2020-2674)

  - 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 as well as unauthorized read access to a subset of Oracle
    VM VirtualBox accessible data. (CVE-2020-2678)

  - A denial of service (DoS) vulnerability exists in the Oracle Virtualization Core component. An
    authenticated, local attacker can exploit this issue, to cause a hang or frequently repeatable crash
    (complete DoS) of Oracle VM VirtualBox. (CVE-2020-2703)");
