DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service).
The vulnerability is caused due to a validation error when processing
certain machine instructions. This can be exploited to cause the
Hyper-V server and all guest virtual machines to stop responding via
a specially crafted packet sent to the VMBus communication channel.
Successful exploitation requires local logon privileges within a
guest virtual machine.
SOLUTION:
Apply patches.
