Flaw in Virtualization Software Could Lead to VM Escapes, Data Theft

Researchers have uncovered a vulnerability in an obscure component of many virtualization platforms that they say can allow an attacker to escape from a guest virtual machine and gain code execution on the host, as well as any other VMs operating on that machine. Experts say the bug affects a wid...
