Descriptions
libndp before 1.6, as used in NetworkManager, does not properly validate the origin of Neighbor Discovery Protocol (NDP) messages, which allows remote attackers to conduct man-in-the-middle attacks or cause a denial of service (network connectivity disruption) by advertising a node as a router from a non-local network.
libndp en versiones anteriores a 1.6, como es usado en NetworkManager, no valida correctamente el origen de los mensajes Neighbor Discovery Protocol (NDP), lo que provoca a atacantes remotos llevar a cabo ataques man-in-the-middle o provocar una caída del servicio (interrupción de la conectividad de red) anunciando un nodo como un router de una red no local.
It was found that libndp did not properly validate and check the origin of Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local network could use this flaw to advertise a node as a router, allowing them to perform man-in-the-middle attacks on a connecting client, or disrupt the network connectivity of that client.
