Descriptions

If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.

Si se utiliza texto de derecha a izquierda en la barra de direcciones con alineación de izquierda a derecha, en algunas circunstancias es posible desplazar este texto para falsificar la URL mostrada. Este problema puede provocar que se muestre una URL incorrecta como ubicación, lo que puede inducir a los usuarios a error al creer que se encuentran en un sitio diferente al que se ha cargado. Esta vulnerabilidad afecta a las versiones anteriores a la 52.6 de Thunderbird, las versiones anteriores a la 52.6 de Firefox ESR y las versiones anteriores a la 58 de Firefox.
