Descriptions

The cat6000-dot1x component in Cisco IOS 12.2 before 12.2(33)SXI7 does not properly handle an external loop between a pair of dot1x enabled ports, which allows remote attackers to cause a denial of service (traffic storm) via unspecified vectors that trigger many unicast EAPoL Protocol Data Units (PDUs), aka Bug ID CSCtq36336.

El componente cat6000-dot1x en Cisco IOS v12.2 anterior a v12.2(33)SXI7 no controla correctamente un bucle externo entre un par de puertos dot1x habilitados, lo que permite a atacantes remotos provocar una denegación de servicio (tormenta de tráfico) a través de vectores no especificados que desencadenan muchas EAPoL Protocol Data Units ( PDUs) unicast, también conocido como Bug ID CSCtq36336.
