The remote host contains a version of Sun xVM VirtualBox, an open source virtualization platform, before 1.6.4. Such versions reportedly include a kernel driver, âVBoxDrv.sysâ, that allows a local user to open the device â\.\VBoxDrvâ and issue IOCTLs with a buffering method of âMETHOD_NEITHERâ without any validation. Using specially crafted input, an unprivileged user can leverage this issue to execute arbitrary code in kernel mode.
