"value": "A vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to cause a crash of the iosd process, causing a denial of service (DoS) condition. The vulnerability is due to insufficient error handling when the BFD header in a BFD packet is incomplete. An attacker could exploit this vulnerability by sending a crafted BFD message to or across an affected switch. A successful exploit could allow the attacker to trigger a reload of the system. This vulnerability affects Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5), Catalyst 4948E Ethernet Switch (K5).

"value": "Una vulnerabilidad en la implementaci\u00f3n de la descarga Bidirectional Forwarding Detection (BFD) de Cisco Catalyst 4500 Series Switches y Cisco Catalyst 4500-X Series Switches podr\u00eda permitir que un atacante remoto no autenticado provoque el cierre inesperado del proceso iosd, lo que provocar\u00eda una denegaci\u00f3n de servicio (DoS). La vulnerabilidad se debe a la gesti\u00f3n insuficiente de errores cuando la cabecera BFD de un paquete BFD est\u00e1 incompleta. Un atacante podr\u00eda explotar esta vulnerabilidad enviando un mensaje BFD manipulado a un switch afectado o a trav\u00e9s de \u00e9l. Un exploit con \u00e9xito podr\u00eda permitir que el atacante cause el reinicio del sistema. Esta vulnerabilidad afecta a Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5) y Catalyst 4948E Ethernet Switch (K5).
