Descriptions

Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.

Firefox aceptará cualquier ID de programa registrado como gestor de protocolo externo y ofrecerá lanzar esta aplicación local cuando se le proporcione una URL correspondiente en los sistemas operativos Windows. Esto sólo debería ocurrir si el programa se ha registrado específicamente como un "manejador de URL" en el registro de Windows. *Nota: Este problema sólo afecta a los sistemas operativos Windows. Otros sistemas operativos no se ven afectados.*. Esta vulnerabilidad afecta a Thunderbird < 60.6, Firefox ESR < 60.6 y Firefox < 66.
