      "value": "A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r This vulnerability is due to insufficient validation of received IPv4 PIMv2 packets. An attacker could exploit this vulnerability by sending a crafted PIMv2 packet to a PIM-enabled interface on an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition.\r\n\r Note: This vulnerability can be exploited with either an IPv4 multicast or unicast packet."

      "value": "Una vulnerabilidad en la funci\u00f3n de multidifusi\u00f3n independiente del protocolo (PIM) del 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. Esta vulnerabilidad se debe a una validaci\u00f3n insuficiente de los paquetes PIMv2 IPv4 recibidos. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando un paquete PIMv2 manipulado a una interfaz habilitada para PIM en un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir que el atacante haga que un dispositivo afectado se recargue, lo que da como resultado una condici\u00f3n de denegaci\u00f3n de servicio. Nota: Esta vulnerabilidad se puede aprovechar con un paquete de multidifusi\u00f3n o unidifusi\u00f3n IPv4."
