The implementation of realpath in libuv < 10.22.1, < 12.18.4, and < 14.9.0 used within Node.js incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.
La implementación de realpath en libuv versiones anteriores a versiones anteriores a 10.22.1, versiones anteriores a 12.18.4 y versiones anteriores a 14.9.0, usada dentro de Node.js determinó incorrectamente el tamaño del búfer, lo que puede resultar en un desbordamiento del búfer si la ruta resuelta tiene más de 256 bytes
