What is CVE-2009-1542?

The Virtual Machine Monitor (VMM) in Microsoft Virtual PC and Microsoft Virtual Server allows unprivileged users in guest operating systems to execute arbitrary kernel-mode code. This occurs due to the VMM not enforcing CPU privilege-level requirements for certain machine instructions. By using specially crafted applications, an attacker can gain elevated privileges within the guest OS, potentially leading to unauthorized access and system control.
