Descriptions

Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs.

Cisco IOS 12.0, 12.1, y 12.2, cuando la tunelación GRE IP esta siendo usada y falta la conformidad RFC2784, no verifica el campo offset de un paquete GRE durante su encapsulación, lo cauls lleva a un desbordamiento de enteros que referencia datos desde localizaciones de memoria incorrectas, lo cual permite a un atacante remoto inyectar paquetes artesanales dentro de la cola de enrutamiento, posiblemente evitando la ACLs del router previsto.
