CVE-2006-2538

Estado: ModificadaBaja (2.6)—

El complemento IE Tab 1.0.9 para Mozilla Firefox 1.5.0.3 permite a atacantes remotos con la asistencia del usuario provocar una denegación de servicio (fallo de la aplicación), posiblemente debido a una desreferencia de puntero nulo, mediante determinado código Javascript, como se demuestra utilizando un parámetro url en la página content/reloaded.html en un URI chrome://. Algunos investigadores externos afirman que no son capaces de reproducir esta vulnerabilidad.
