Descriptions

A vulnerability in the OSPF version 2 (OSPFv2) feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of OSPF updates that are processed by a device. An attacker could exploit this vulnerability by sending a malformed OSPF update to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

Una vulnerabilidad en la característica OSPF versión 2 (OSPFv2) del software Cisco IOS XE podría permitir que un atacante adyacente no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS).
