      "value": "A vulnerability in the Local Packet Transport Services (LPTS) ingress frame-processing functionality of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause one of the LPTS processes on an affected system to restart unexpectedly, resulting in a brief denial of service (DoS) condition. The vulnerability is due to incomplete LPTS frame validation by the affected software. An attacker could exploit this vulnerability by sending crafted XML requests to the management interface of an affected system. A successful exploit could allow the attacker to cause one of the LPTS processes on the affected system to restart unexpectedly, which would impact LPTS traffic and cause a brief DoS condition while the process restarts.

Esto resulta en una breve condición de denegación de servicio (DoS). Esta vulnerabilidad también se debe a la validación incompleta de frames LPTS por parte del software afectado. Un atacante podría explotar esta vulnerabilidad enviando peticiones XML manipuladas a la interfaz de gestión de un sistema afectado. Un exploit con éxito podría permitir que el atacante provoque que uno de los procesos LPTS en el sistema afectado se reinicie inesperadamente, lo que impactaría el tráfico LPTS y provocaría una breve condición de DoS mientras se reinicia el proceso.
