Revision Note: V2.0 (October 13, 2015): Advisory revised to notify customers that an update is available that modifies the Code Integrity component in Windows to extend trust removal for the four digital certificates addressed by this advisory to also preclude kernel-mode code signing.
Summary: Microsoft is aware of four digital certificates that were inadvertently disclosed by D-Link Corporation that could be used in attempts to spoof content. The disclosed end-entity certificates cannot be used to issue other certificates or impersonate other domains, but could be used to sign code. This issue affects all supported releases of Microsoft Windows.
