      "value": "Contiki-NG is an open-source, cross-platform operating system for internet of things devices. A buffer overflow vulnerability exists in Contiki-NG versions prior to 4.6. After establishing a TCP socket using the tcp-socket library, it is possible for the remote end to send a packet with a data offset that is unvalidated. The problem has been patched in Contiki-NG 4.6. Users can apply the patch for this vulnerability out-of-band as a workaround."

Se presenta una vulnerabilidad de desbordamiento de b\u00fafer en las versiones de Contiki-NG anteriores a 4.6. Despu\u00e9s de haber establecido un socket TCP usando la biblioteca tcp-socket, es posible para el extremo remoto enviar un paquete con un desplazamiento de datos que no est\u00e1 validado. El problema ha sido parcheado en Contiki-NG versi\u00f3n 4.6. Los usuarios pueden aplicar el parche para esta vulnerabilidad fuera de l\u00edmite como soluci\u00f3n alternativa"
