TFSA-2020-021: Heap buffer overflow in SparseFillEmptyRowsGrad

CVE Number

CVE-2020-15195

Impact

The implementation of SparseFillEmptyRowsGrad uses a double indexing pattern:

      d_values(i) = grad_values(reverse_index_map(i));

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.

Vulnerable Versions

TensorFlow 1.15.0, 1.15.1, 1.15.2, 1.15.3, 2.0.0, 2.0.1, 2.0.2, 2.1.0, 2.1.1, 2.2.0, 2.3.0.

Patches

We have patched the issue in 390611e0d45c5793c7066110af37c8514e6a6c54 and will release a patch release for all affected versions.

We recommend users to upgrade to TensorFlow 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.
