Microsoft Security Advisory (2416728): Vulnerability in ASP.NET Could Allow Information Disclosure -
Revision Note: V1.1 (September 20, 2010): Revised Executive Summary to communicate that Microsoft is aware of limited, active attacks. Also added additional entries to the Frequently Asked Questions section and additional clarification to the workaround. Advisory Summary:Microsoft is investigating a new public report of a vulnerability in ASP.NET. An attacker who exploited this vulnerability could view data, such as the View State, which was encrypted by the target server, or read data from files on the target server, such as web.config. This would allow the attacker to tamper with the contents of the data. By sending back the altered contents to an affected server, the attacker could observe the error codes returned by the server. Microsoft is aware of limited, active attacks at this time.

hv_utils

HYPER-V(4)						   BSD Kernel Interfaces Manual 						HYPER-V(4)

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.
