Descriptions
An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. When an unsupported TCP option with zero length is provided in an incoming TCP packet, it is possible to cause a Denial-of-Service by achieving an infinite loop in the code that parses TCP options, aka tcp_parse_options() in pico_tcp.c.
Se detectó un problema en picoTCP y picoTCP-NG versiones hasta 1.7.0. Cuando se proporciona una opción TCP no compatible con longitud cero en un paquete TCP entrante, es posible causar una Denegación de Servicio logrando un bucle infinito en el código que analiza las opciones TCP, también se conoce como la función tcp_parse_options() en el archivo pico_tcp.c
