Descriptions

A vulnerability in the Open Shortest Path First version 3 (OSPFv3) implementation in Cisco IOS and IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. The vulnerability is due to incorrect handling of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending crafted OSPFv3 Link-State Advertisements (LSA) to an affected device. An exploit could allow the attacker to cause an affected device to reload, leading to a denial of service (DoS) condition.

Una vulnerabilidad en la implementación de Open Shortest Path First version 3 (OSPFv3) en Cisco IOS e IOS XE Software podría permitir que un atacante adyacente sin autenticar provoque que un dispositivo afectado se reinicie. Esta vulnerabilidad se debe a una gestión incorrecta de paquetes OSPFv3 específicos. Un atacante podría explotar esta vulnerabilidad enviando LSA (Link-State Advertisements) OSPFv3 a un dispositivo afectado. Su explotación podría permitir que el atacante consiga que el dispositivo afectado se reinicie, creando una condición de denegación de servicio (DoS).
