Descriptions

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.

En Tensorflow versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, la implementación de "SparseFillEmptyRowsGrad" usa un patrón de indexación doble. Es posible que "reverse_index_map (i)" sea un índice fuera de los límites de "grad_values", lo que resulta en un desbordamiento del búfer de la pila. El problema es parcheado en el commit 390611e0d45c5793c7066110af37c8514e6a6c54 y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1
