high Nessus Plugin ID 83729
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host has an application that is affected by a remote code execution vulnerability.


The remote host contains a version of Oracle VM VirtualBox that is prior to 3.2.28 / 4.0.30 / 4.1.38 / 4.2.30 / 4.3.28. It is, therefore affected by a flaw in the Floppy Disk Controller (FDC) in the bundled QEMU software due to an overflow condition in 'hw/block/fdc.c' when handling certain commands. An attacker, with access to an account on the guest operating system with privilege to access the FDC, can exploit this flaw to execute arbitrary code in the context of the hypervisor process on the host system.


Upgrade Oracle VM VirtualBox to 3.2.28 / 4.0.30 / 4.1.38 / 4.2.30 / 4.3.28 or later.
