Descriptions

A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the PIM process to restart, resulting in a denial of service condition on an affected device. The vulnerability is due to the incorrect processing of crafted AutoRP packets. An attacker could exploit this vulnerability by sending crafted packets to port UDP 496 on a reachable IP address on the device. A successful exploit could allow the attacker to cause the PIM process to restart. Software versions prior to 6.2.3, 6.3.2, 6.4.0, and 6.5.1 are affected.

Una vulnerabilidad en la característica de Protocolo (Protocol Independent Multicast (PIM) Independent Multicast (PIM) del programa Cisco IOS XR podría permitir que un atacante remoto no identificado haga que el proceso de PIM se reinicie, lo que resulta en una condición de Denegación de Servicio (DoS) en un dispositivo afectado. La vulnerabilidad se debe al procesamiento incorrecto de los paquetes de AutoRP creados. Un atacante podría aprovechar esta vulnerabilidad enviando paquetes creados al puerto UDP 496 en una dirección IP accesible en el dispositivo. Una explotación exitosa podría permitir al atacante hacer que el proceso PIM se reinicie. Las versiones del programa anteriores a 6.2.3, versión 6.3.2,versión 6.4.0 y versión 6.5.1 están afectadas.
