Heap OOB read in TFLite's implementation of Minimum or Maximum

Impact

The implementations of the Minimum and Maximum TFLite operators can be used to read data outside of bounds of heap allocated objects, if any of the two input tensor arguments are empty.

This is because the broadcasting implementation indexes in both tensors with the same index but does not validate that the index is within bounds:

auto maxmin_func = [&](int indexes[N]) { output_data[SubscriptToIndex(output_desc, indexes)] = op(input1_data[SubscriptToIndex(desc1, indexes)], input2_data[SubscriptToIndex(desc2, indexes)]); };

Patches

We have patched the issue in GitHub commit 953f28dca13c92839ba389c055587cfe6c723578.

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.

TensorFlow is an end-to-end open source platform for machine learning. The implementations of the `Minimum` and `Maximum` TFLite operators can be used to read data outside of bounds of heap allocated objects, if any of the two input tensor arguments are empty. This is because the broadcasting implementation(https://github.com/tensorflow/tensorflow/blob/0d45ea1ca641b21b73bcf9c00e0179cda284e7e7/tensorflow/lite/kernels/internal/reference/maximum_minimum.h#L52-L56) indexes in both tensors with the same index but does not validate that the index is within bounds.
