CVE-2021-29520 Information

Description

TensorFlow is an end-to-end open source platform for machine learning. Missing validation between arguments to tf.raw_ops.Conv3DBackprop operations can result in heap buffer overflows. This is because the implementation(https://github.com/tensorflow/tensorflow/blob/4814fafb0ca6b5ab58a09411523b2193fed23fed/tensorflow/core/kernels/conv_grad_shape_utils.ccL94-L153) assumes that the input filter_sizes and out_backprop tensors have the same shape as they are accessed in parallel. 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.
