      "value": "RIOT 2020.04 has a buffer overflow in the base64 decoder. The decoding function base64_decode() uses an output buffer estimation function to compute the required buffer capacity and validate against the provided buffer size. The base64_estimate_decode_size() function calculates the expected decoded size with an arithmetic round-off error and does not take into account possible padding bytes. Due to this underestimation, it may be possible to craft base64 input that causes a buffer overflow."

      "value": "RIOT versi\u00f3n 2020.04, presenta un desbordamiento del b\u00fafer en el decodificador base64. La funci\u00f3n de decodificaci\u00f3n base64_decode() usa una funci\u00f3n de estimaci\u00f3n del b\u00fafer de salida para calcular la capacidad de b\u00fafer requerida y comprobarla con el tama\u00f1o del b\u00fafer proporcionado. La funci\u00f3n base64_estimate_decode_size() calcula el tama\u00f1o descodificado esperado con un error de redondeo aritm\u00e9tico y no toma en cuenta los posibles bytes de relleno. Debido a esta subestimaci\u00f3n, puede ser posible crear una entrada base64 que cause un desbordamiento del b\u00fafer"
