Descriptions

If the "app.support.baseURL" preference is changed by a malicious local program to contain HTML and script content, this content is not sanitized. It will be executed if a user loads "chrome://browser/content/preferences/in-content/preferences.xul" directly in a tab and executes a search. This stored preference is also executed whenever an EME video player plugin displays a CDM-disabled message as a notification message. This vulnerability affects Firefox < 59.

Si un programa local malicioso cambia la preferencia "app.support.baseURL" para que contenga contenido HTML y script, este contenido no se sanea. Se ejecutará si un usuario carga "chrome://navegador/content/preferences/in-content/preferences.xul" directamente en una pestaña y ejecuta una búsqueda. Esta preferencia almacenada también se ejecuta siempre que un plugin del reproductor de vídeo de EME muestre un mensaje CDM deshabilitado como mensaje de notificación. Esta vulnerabilidad afecta a las versiones anteriores a la 59 de Firefox.
