Descriptions

A vulnerability in the Cisco Umbrella Integration feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition, related to the OpenDNS software. The vulnerability is due to a logic error that exists when handling a malformed incoming packet, leading to access to an internal data structure after it has been freed. An attacker could exploit this vulnerability by sending crafted, malformed IP packets to an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvb86327.

Una vulnerabilidad en la característica Cisco Umbrella Integration en Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS), relacionada con el software OpenDNS. La vulnerabilidad se debe a un error de lógica que existe al manipular un paquete entrante mal formado, lo que conduce al acceso a una estructura de datos interna una vez se ha liberado. Un atacante podría explotar esta vulnerabilidad enviando paquetes IP mal formados y manipulados a un dispositivo afectado. Si se explota con éxito, podría permitir que el atacante consiga que el dispositivo afectado se reinicie, provocando una denegación de servicio. Cisco Bug IDs: CSCvb86327.
