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 encapsulated packets sent to the VMBus communication channel. This can be exploited to cause the Hyper-V server and all guest virtual machines to stop responding via a specially crafted packet.

Successful exploitation requires an attacker to have local logon privileges within a guest virtual machine.


Solution:
Apply patches.
