Causa ra\u00edz: En el c\u00f3digo del analizador de protocolo Redis de bRPC, la memoria para matrices o cadenas de tama\u00f1os correspondientes se asigna en funci\u00f3n de los enteros le\u00eddos de la red. Si el entero le\u00eddo de la red es demasiado grande, puede causar un error de asignaci\u00f3n incorrecta y provocar el bloqueo del programa. Los atacantes pueden explotar esta caracter\u00edstica enviando paquetes de datos especiales al servicio bRPC para llevar a cabo un ataque de denegaci\u00f3n de servicio. La versi\u00f3n bRPC 1.14.0 intent\u00f3 solucionar este problema limitando el tama\u00f1o de la asignaci\u00f3n de memoria; sin embargo, el c\u00f3digo de comprobaci\u00f3n de limitaciones no est\u00e1 bien implementado, lo que puede causar un desbordamiento de enteros y evadir dicha limitaci\u00f3n.
