Virtual machine escape

In computer security, virtual machine escape is the process of breaking out of a virtual machine and interacting with the host operating system.[1] A virtual machine is a "completely isolated guest operating system installation within a normal host operating system".[2] In 2008, a vulnerability (CVE-2008-0923) in VMware discovered by Core Security Technologies made VM escape possible on VMWare Workstation 6.0.2 and 5.5.4.[3][4] A fully working exploit labeled Cloudburst was developed by Immunity Inc. for Immunity CANVAS (commercial penetration testing tool).[5] Cloudburst was presented in Black Hat USA 2009.[6]
