Descriptions

TensorFlow is an open source platform for machine learning. In affected versions if `tf.tile` is called with a large input argument then the TensorFlow process will crash due to a `CHECK`-failure caused by an overflow. The number of elements in the output tensor is too much for the `int64_t` type and the overflow is detected via a `CHECK` statement. This aborts the process. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.

TensorFlow es una plataforma de código abierto para el aprendizaje automático. En las versiones afectadas, si se llama a "tf.tile" con un argumento de entrada grande, el proceso de TensorFlow será bloqueado debido a un fallo de "CHECK" causado por un desbordamiento. El número de elementos en el tensor de salida es demasiado para el tipo "int64_t" y el desbordamiento es detectado por medio de una sentencia "CHECK". Esto aborta el proceso. La corrección será incluida en TensorFlow versión 2.7.0. También será incluida este commit en TensorFlow versión 2.6.1, TensorFlow versión 2.5.2, y TensorFlow versión 2.4.4, ya que estos también están afectados y todavía están en el rango admitido
