CVE-2021-29519: TensorFlow is an end-to-end open source platform for machine learning. The API of `tf.raw_ops.SparseCross` allows combin
Summary
TensorFlow, a machine learning platform, has a vulnerability in its `tf.raw_ops.SparseCross` function that can crash a program (denial of service) by tricking the code into mixing incompatible data types (string type with integer type). The vulnerability occurs because the implementation incorrectly processes a tensor, thinking it contains one type of data when it actually contains another.
Solution / Mitigation
The fix prevents mixing `DT_STRING` and `DT_INT64` types and will be included in TensorFlow 2.5.0. The fix will also be applied to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3, and TensorFlow 2.1.4.
