General Information

Executive Summary

This security update resolves one publicly disclosed vulnerability in

configured, and then its configuration details (farm certificate) shared with
other users.

This security update is rated Moderate for Microsoft Service Bus 1.1 when 
installed on affected editions of Windows Server 2008 R2, Windows Server 2012,
