The vulnerability is due to improper handling of UDP broadcast packets that are forwarded to an IPv4 helper address. An attacker could exploit this vulnerability by sending multiple UDP broadcast packets to the affected device. An exploit could allow the attacker to cause a buffer leak on the affected device, eventually resulting in a DoS condition requiring manual intervention to recover. This vulnerability affects all Cisco IOS XR platforms running 6.3.1, 6.2.3, or earlier releases of Cisco IOS XR Software when at least one IPv4 helper address is configured on an interface of the device.

La vulnerabilidad se debe a la gesti\u00f3n incorrecta de los paquetes de transmisi\u00f3n UDP que se reenv\u00edan a una direcci\u00f3n auxiliar IPv4. Un atacante podr\u00eda explotar esta vulnerabilidad enviando m\u00faltiples paquetes de transmisi\u00f3n UDP a un dispositivo afectado. Un exploit podr\u00eda permitir que el atacante provoque una fuga del b\u00fafer en el dispositivo afectado, lo que resultar\u00eda finalmente en una denegaci\u00f3n de servicio (DoS) que requerir\u00eda una intervenci\u00f3n manual para recuperarla.
