Descriptions

The PPAPI implementation in Google Chrome before 52.0.2743.82 does not validate the origin of IPC messages to the plugin broker process that should have come from the browser process, which allows remote attackers to bypass a sandbox protection mechanism via an unexpected message type, related to broker_process_dispatcher.cc, ppapi_plugin_process_host.cc, ppapi_thread.cc, and render_frame_message_filter.cc.

La implementación PPAPI en Google Chrome en versiones anteriores a 52.0.2743.82 no valida el origen de los mensajes IPC para el plugin del proceso broker que debería haber llegado desde el proceso navegador, lo que permite a atacantes remotos eludir un mecanismo de protección sandbox a través de un tipo de mensaje inesperado, relacionado con broker_process_dispatcher.cc, ppapi_plugin_process_host.cc, ppapi_thread.cc y render_frame_message_filter.cc.
