CVE-2018-5172

Estado: ModificadaMedia (4.3)—

La página Live Bookmarks y el visor de PDF pueden ejecutar contenido de scripts inyectados si un usuario pega el script del portapapeles en ellos mientras visualiza fuentes RSS o archivos PDF. Esto podría permitir a un sitio malicioso realizar ingeniería social en un usuario para copiar y pegar contenido de secuencias de comandos maliciosos que podrían ejecutarse con el contexto de cualquiera de las páginas, pero que no permite el escalado de privilegios. Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
