CVE-2021-29586: TensorFlow is an end-to-end open source platform for machine learning. Optimized pooling implementations in TFLite fail

TensorFlow's pooling code (the part that downsamples data in neural networks) has a bug where it doesn't check if stride values, which control how much data to skip, are zero before doing math with them. An attacker can create a special machine learning model that forces stride to be zero, causing a division by zero error (dividing by zero, which crashes programs) that could crash or be exploited.
