      "value": "free5GC is an open-source project for 5th generation (5G) mobile core networks. Versions up to and including 1.4.1 of free5GC\u0027s AMF service have a Buffer Overflow vulnerability leading to Denial of Service. Remote unauthenticated attackers can crash the AMF service by sending a specially crafted NAS Registration Request with a malformed 5GS Mobile Identity, causing complete denial of service for the 5G core network. All deployments of free5GC using the AMF component may be affected. Pull request 43 of the free5gc/nas repo contains a fix. No direct workaround is available at the application level. Applying the official patch is recommended."

Los atacantes remotos no autenticados pueden bloquear el servicio AMF enviando una solicitud de registro NAS especialmente dise\u00f1ada con una identidad m\u00f3vil 5GS malformada, causando una denegaci\u00f3n de servicio completa para la red central 5G. Todas las implementaciones de free5GC que utilizan el componente AMF pueden verse afectadas. La solicitud de extracci\u00f3n 43 del repositorio free5gc/nas contiene una correcci\u00f3n. No hay una soluci\u00f3n alternativa directa disponible a nivel de aplicaci\u00f3n. Se recomienda aplicar el parche oficial."
