Descriptions

The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in FreeBSD, NetBSD, and possibly other BSD-based operating systems allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, a similar vulnerability to CVE-2010-4670.

La implementación del protocolo de descubrimiento de vecinos (Neighbor Discovery - ND) en la pila IPv6 en FreeBSD, NetBSD, y posiblemente, otros sistemas operativos basados ??en BSD permite a atacantes remotos provocar una denegación de servicio (consumo de CPU y bloqueo del dispositivo) mediante el envío de muchos mensajes de anuncio de enrutador (Router Advertisemente - RA) con direcciones de origen diferente. Se trata de una vulnerabilidad similar a CVE-2010-4670.
