Descriptions

Tensorflow is an Open Source Machine Learning Framework. In multiple places, TensorFlow uses `tempfile.mktemp` to create temporary files. While this is acceptable in testing, in utilities and libraries it is dangerous as a different process can create the file between the check for the filename in `mktemp` and the actual creation of the file by a subsequent operation (a TOC/TOU type of weakness). In several instances, TensorFlow was supposed to actually create a temporary directory instead of a file. This logic bug is hidden away by the `mktemp` function usage. We have patched the issue in several commits, replacing `mktemp` with the safer `mkstemp`/`mkdtemp` functions, according to the usage pattern. Users are advised to upgrade as soon as possible.

Tensorflow es un Marco de Aprendizaje Automático de Código Abierto. En varios lugares, TensorFlow usa "tempfile.mktemp" para crear archivos temporales. Mientras que esto es aceptable en las pruebas, en las utilidades y bibliotecas es peligroso ya que un proceso diferente puede crear el archivo entre la comprobación del nombre del archivo en "mktemp" y la creación real del archivo por una operación posterior (una debilidad del tipo TOC/TOU). En varios casos, se supone que TensorFlow debería crear un directorio temporal en lugar de un archivo. Este error lógico está oculto por el uso de la función "mktemp". Hemos parcheado el problema en varios commits, sustituyendo "mktemp" por las funciones más seguras "mkstemp"/"mkdtemp", de acuerdo con el patrón de uso. Se recomienda a usuarios que actualicen lo antes posible
