    • (December 12, 2013) Microsoft has released KB2871690 which is an update for Windows 8 and Windows Server 2012 that revokes the digital signatures for nine private, third-party UEFI (Unified Extensible Firmware Interface) modules that could be loaded during UEFI Secure Boot. When the update is applied, the affected UEFI modules will no longer be trusted and will no longer load on systems where UEFI Secure Boot is enabled. The affected UEFI modules consist of specific Microsoft-signed modules that are either not in compliance with our certification program or their authors have requested that the packages be revoked. At the time of this release, these UEFI modules are not known to be available publicly.

     

    • Microsoft is not aware of any misuse of the affected UEFI modules. Microsoft is proactively revoking these non-compliant modules as part of ongoing efforts to protect customers. This action only affects systems running Windows 8 and Windows Server 2012 that are capable of UEFI Secure Boot where the system is configured to boot via UEFI and Secure Boot is enabled. There is no action on systems that do not support UEFI Secure Boot or where it is disabled.
