An attacker could exploit this vulnerability by sending specific sizes of fragmented packets to an affected device or through a Virtual Fragmentation Reassembly (VFR)-enabled interface on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.\r\n\r Note: This vulnerability affects Cisco ASR 1000 Series Aggregation Services Routers and Cisco cBR-8 Converged Broadband Routers if they are running Cisco IOS XE Software Release 17.12.1 or 17.12.1a."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n del c\u00f3digo de reensamblado de fragmentaci\u00f3n de IPv4 en el software Cisco IOS XE podr\u00eda permitir que un atacante remoto no autenticado provoque una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
