Descriptions

Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.

Desbordamiento de enteros en la función visual_read en wiretap/visual.c de Wireshark v1.2.x con anterioridad a v1.2.17 y v1.4.x con anterioridad a v1.4.7 permite a atacantes remotos provocar una denegación de servicio ( caída de la aplicación) a través de un archivo mal formado de Visual Networks que desencadena una sobre-lectura del buffer de memoria dinámica.
