Revision Note: V2.0 (October 14, 2014): Bulletin rereleased to announce the offering of the security update via Microsoft Update, in addition to the Download-Center-only option that was provided when this bulletin was originally released.
Summary: This security update resolves one publicly disclosed vulnerability in Microsoft Service Bus for Windows Server. The vulnerability could allow denial of service if a remote authenticated attacker creates and runs a program that sends a sequence of specially crafted Advanced Message Queuing Protocol (AMQP) messages to the target system. Microsoft Service Bus for Windows Server is not shipped with any Microsoft operating system. For an affected system to be vulnerable Microsoft Service Bus must first be downloaded, installed, and configured, and then its configuration details (farm certificate) shared with other users.
