Summary
A vulnerability in the Internet Key Exchange version 2 (IKEv2) function of Cisco IOS XR Software could allow an unauthenticated, remote attacker to prevent an affected device from processing any control plane UDP packets.  This vulnerability is due to improper handling of malformed IKEv2 packets. An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected device. A successful exploit could allow the attacker to prevent the affected device from processing any control plane UDP packets, resulting in a denial of service (DoS) condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Esta vulnerabilidad se debe a la gestión incorrecta de paquetes IKEv2 malformados. Un atacante podría explotar esta vulnerabilidad enviando paquetes IKEv2 malformados a un dispositivo afectado. Una explotación exitosa podría permitir al atacante impedir que el dispositivo afectado procese paquetes UDP del plano de control, lo que provocaría una denegación de servicio (DoS). Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que la solucionen.",
