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."}, {"lang": "es", "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.
