Virtualization Vulnerabilities Up And Coming

Microsoft's February 2010 Patch Tuesday was one of the bigger releases for Microsoft and its clients in the past two years -- 13 bulletins addressing 26 vulnerabilities.

Microsoft's February 2010 Patch Tuesday was one of the bigger releases for Microsoft and its clients in the past two years -- 13 bulletins addressing 26 vulnerabilities.We have recommended to our customers to focus on updates MS10-006 SMB client and MS10-013 DirectShow because they affect all versions of Windows and can be exploited easily by attackers. Also important are MS10-003 and MS10-004, which are updates to the older versions of the Microsoft Office family. These vulnerabilities can be readily exploited simply by sending malicious documents (Office and PPTs) to users.

One of the less critical vulnerabilities, rated only as Important, is nevertheless quite interesting: MS10-010, which addresses a vulnerability in the virtualization component of Windows 2008: the hypervisor. The flaw enables a guest operating system running under the hypervisor to crash the Windows 2008 host, affecting all virtual machines running on the same host. The vulnerability falls short of the real goal: controlling the host operating system and being able to exploit the other guest operating systems hosted on the same physical machine. Still, this is a sign that we will see more significant vulnerabilities in the near future affecting virtualization technologies. Specialized security researchers have been working for years on virtualization, and we have seen impressive results being presented and discussed -- most notably by Joanna Rutkowska's Red/Blue Pill and Kortchinsky's CloudBurst presentations at BlackHat.

Virtualization is increasingly becoming an important building block for corporate server infrastructures, and it is a key technology used in many cloud computing initiatives, primarily in the Infrastructure-as-a-Service (IaaS) arena. IT administrators need to acknowledge this technology as a first-class operating system that requires its own monitoring toolset, dedicated security procedures, and hardening policies.
