"value": "When mounting a remote filesystem using NFS, the kernel did not sanitize remotely provided filenames for the path separator character, \"/\". This allows readdir(3) and related functions to return filesystem entries with names containing additional path components.\n\nThe lack of validation described above gives rise to a confused deputy problem. For example, a program copying files from an NFS mount could be tricked into copying from outside the intended source directory, and/or to a location outside the intended destination directory."

"value": "Al montar un sistema de archivos remoto usando NFS, el kernel no desinfect\u00f3 los nombres de archivos proporcionados de forma remota para el car\u00e1cter separador de ruta, \"/\". Esto permite que readdir(3) y funciones relacionadas devuelvan entradas del sistema de archivos con nombres que contienen componentes de ruta adicionales. La falta de validaci\u00f3n descrita anteriormente da lugar a un confuso problema de diputados. Por ejemplo, se podr\u00eda enga\u00f1ar a un programa que copia archivos desde un montaje NFS para que los copie desde fuera del directorio de origen previsto y/o a una ubicaci\u00f3n fuera del directorio de destino previsto."
