Descriptions

The tunnels implementation in the Linux kernel before 2.6.34, when tunnel functionality is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading.

La implementación de túneles ("tunnels") del kernel de Linux en versiones anteriores a la 2.6.34, si la funcionalidad de túneles está configurada como módulo, permite a atacantes remotos provocar una denegación de servicio (OOPS) enviando un paquete durante la carga del módulo.
