CVE-2021-37650

Advisory

Intel-tensorflow 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37650: In affected versions the implementation for `tf.raw_ops.ExperimentalDatasetToTFRecord` and `tf.raw_ops.DatasetToTFRecord` can trigger heap buffer overflow and segmentation fault. The [implementation](https://github.com/tensorflow/tensorflow/blob/f24faa153ad31a4b51578f8181d3aaab77a1ddeb/tensorflow/core/kernels/data/experimental/to_tf_record_op.cc#L93-L102) assumes that all records in the dataset are of string type. However, there is no check for that, and the example given above uses numeric types. The Tensorflow team has patched the issue in GitHub commit e0b6e58c328059829c3eb968136f17aa72b6c876.
