details: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the
  implementation of `SparseFillEmptyRowsGrad` uses a double indexing pattern. It is
  possible for `reverse_index_map(i)` to be an index outside of bounds of `grad_values`,
  thus resulting in a heap buffer overflow. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54,
  and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.
