CVE-2021-29618

TensorFlow is an end-to-end open source platform for machine learning. Passing a complex argument to tf.transpose at the same time as passing conjugate=True argument results in a crash. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
