CVE-2006-3357

Estado: ModificadaAlta (7.5)—

Desbordamiento del búfer de memoria libre para la reserva dinámica en HTML Help ActiveX control (hhctrl.ocx) en Microsoft Internet Explorer 6.0, que permite a los atacantes remotos provocar la denegación de servicios (caída de la aplicación) y posiblemente la ejecución de código arbitrario, estableciendo repetidamente el campo de imagen de un objeto Internet.HHCtrl.1 a determinados valores, posiblemente relacionados con salidas incorrectas y cadenas largas.
