Descriptions

The snoop_read function in wiretap/snoop.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 does not properly handle certain virtualizable buffers, which allows remote attackers to cause a denial of service (application crash) via a large length value in a snoop file that triggers a stack-based buffer over-read.

La función snoop_read en wiretap/snoop.c de Wireshark v1.2.x antes de v1.2.17 y v1.4.x antes de v1.4.7 no maneja adecuadamente ciertos búfers virtualizables, que permite a atacantes remotos provocar una denegación de servicio ( caída de aplicación) a través de un valor de longitud grande en un archivo de Snoop que desencadena un búfer una sobre-lectura en la pila del búfer.
