Descriptions

Sites can bypass security checks on permissions to install lightweight themes by manipulating the "baseURI" property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.

Los sitios pueden omitir las comprobaciones de seguridad de los permisos para instalar temas ligeros manipulando la propiedad "baseURI" del elemento theme. Esto podría permitir que un sitio malicioso instale un tema sin la interacción del usuario que podría contener imágenes ofensivas o embarazosas. Esta vulnerabilidad afecta a las versiones anteriores a la 52.8 de Thunderbird, las versiones anteriores a la 52.8 de Thunderbird ESR, las versiones anteriores a la 60 de Firefox y las versiones anteriores a la 52.8 de Firefox ESR.
