Descriptions
An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing function in pico_tcp.c does not validate the length of incoming TCP packets, which leads to an out-of-bounds read when assembling received packets into a data segment, eventually causing Denial-of-Service or an information leak.
Se detectó un problema en picoTCP y picoTCP-NG versiones hasta 1.7.0. La función de procesamiento de datos de entrada TCP en el archivo pico_tcp.c no comprueba la longitud de los paquetes TCP entrantes, lo que conlleva a una lectura fuera de límites al ensamblar los paquetes recibidos en un segmento de datos, eventualmente causando una Denegación de Servicio o un filtrado de información
