CVE-2014-9766

Estado: ModificadaCrítica (9.8)—

Desbordamiento de entero en la función create_bits en pixman-bits-image.c en Pixman en versiones anteriores a 0.32.6 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de valores grandes de height y stride.
