An independent exploit developer and vulnerability researcher has publicly disclosed a zero-day vulnerability in VirtualBox —a popular open source virtualization software developed by Oracle—that could allow a malicious program to escape virtual machine (guest OS) and execute code on the operating system of the host machine. The vulnerability occurs due to memory corruption issues and affects Intel PRO / 1000 MT Desktop (82540EM) network card (E1000) when the network mode is set to NAT (Network Address Translation). The flaw is independent of the type of operating system being used by the virtual and host machines because it resides in a shared code base. VirtualBox Zero-Day Exploit and Demo Video Released Sergey Zelenyuk published Wednesday a detailed technical explanation of the zero-day flaw on GitHub, which affects all current versions (5.2.20 and prior) of VirtualBox software and is present on the default Virtual Machine (VM) configuration.
