Microsoft has released<\/a> the second ever<\/em> (since the release of Windows Server 2008!) security fix for Hyper-V.  <\/p>\n

\u201cThis security update resolves a privately reported vulnerability in Windows Server 2008 Hyper-V and Windows Server 2008 R2 Hyper-V. The vulnerability could allow denial of service if a specially crafted packet is sent to the VMBus by an authenticated user in one of the guest virtual machines hosted by the Hyper-V server. An attacker must have valid logon credentials and be able to send specially crafted content from a guest virtual machine to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users\u201d.<\/em><\/p>\n

In other words, you have to be logged into a VM running on the host (be a legit internal user) and have sufficient rights in the VM\u2019s operating system to craft this packet.<\/p>\n

The issue affects Windows Server 2008 and<\/em> Windows Server 2008 R2.<\/p>\n
