The vulnerability is due to the incorrect handling of certain MPLS OAM packets. An attacker could exploit this vulnerability by sending malicious MPLS OAM packets to an affected device. A successful exploit could allow the attacker to cause the lspv_server process to crash. The crash could lead to system instability and the inability to process or forward traffic though the device, resulting in a DoS condition that require manual intervention to restore normal operating conditions."}, {"lang": "es", "value": "Una vulnerabilidad en Multiprotocol Label Switching (MPLS) Operations, Administration, and Maintenance (OAM) implementation of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers, podr\u00eda permitir que un atacante adyacente sin autorizaci\u00f3n active una condici\u00f3n de Denegaci\u00f3n de Servicio (DoS) en un dispositivo afectado.
