CVE-2020-15195
September 25, 2020
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.
