CVE-2021-41218
MEDIUMTensorFlow 2.4.0-2.4.3, 2.6.0 - Divide By Zero in AllToAll Shape Inference
Title source: llmDescription
TensorFlow is an open source platform for machine learning. In affected versions the shape inference code for `AllToAll` can be made to execute a division by 0. This occurs whenever the `split_count` argument is 0. 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.
