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."
