This vulnerability is due to a deadlock condition in the code when processing COPS packets under certain conditions. An attacker could exploit this vulnerability by sending COPS packets with high burst rates to an affected device. A successful exploit could allow the attacker to cause the CPU to consume excessive resources, which prevents other control plane processes from obtaining resources and results in a DoS."}, {"lang": "es", "value": "Una vulnerabilidad en el Servicio de Pol\u00edtica Abierta Com\u00fan (COPS) de Cisco IOS XE Software para Cisco cBR-8 Converged Broadband Routers podr\u00eda permitir a un atacante remoto no autenticado causar el agotamiento de los recursos, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (DoS).
