Revision Note: V1.0 (February 23, 2011): Advisory published. Advisory Summary:Microsoft is releasing this security advisory to help ensure customers are aware that an update to the Microsoft Malware Protection Engine also addresses a security vulnerability reported to Microsoft. The update addresses a privately reported vulnerability that could allow elevation of privilege if the Microsoft Malware Protection Engine scans a system after an attacker with valid logon credentials has created a specially crafted registry key. An attacker who successfully exploited the vulnerability could gain the same user rights as the LocalSystem account. The vulnerability could not be exploited by anonymous users.

NAME

     hv_utils -- Hyper-V Utilities Driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in the system kernel configuration file:

	   device hyperv

DESCRIPTION

     The hv_utils driver provides time keeping, shutdown and heartbeat functionality for FreeBSD guest partitions running on Hyper-V.  Hyper-V is
     a hypervisor-based virtualization technology from Microsoft.  The hv_utils driver is one of the core drivers required to be present in guest
     partitions running on Hyper-V.  This driver provides the following functionalities to guest partitions:

     (a) Time Keeping: The clock inside the guest partition will remain accurate by synchronizing to the clock on the virtualization server via
     Timesync service, and with the help of the pluggable time source device.

     (b) Integrated shutdown: Guest partitions running FreeBSD can be shut down from Hyper-V Manager console by using the "Shut down" command.

     (c) Heartbeat: This feature allows the virtualization server to detect whether the guest partition is running and responsive.
