Impact
The implementation of
SparseFillEmptyRowsGraduses a double indexing pattern:https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/core/kernels/sparse_fill_empty_rows_op.cc#L263-L269
It is possible for
reverse_index_map(i)to be an index outside of bounds ofgrad_values, thus resulting in a heap buffer overflow.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.
