Descriptions

In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `SparseFillEmptyRowsGrad` implementation has incomplete validation of the shapes of its arguments. Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. 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" presenta una comprobación incompleta de las formas de sus argumentos. Aunque se accede a "reverse_index_map_t" y "grad_values_t" con un patrón similar, solo "reverse_index_map_t" se comprueba que tenga la forma adecuada. Por lo tanto, los usuarios maliciosos pueden pasar un "grad_values_t" incorrecto para desencadenar un fallo de aserción en "vec", causando la denegación de servicio en las instalaciones de servicio. 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
