CVE-2021-37656

Advisory

Intel-tensorflow 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37656: In affected versions an attacker can cause undefined behavior via binding a reference to null pointer in 'tf.raw_ops.RaggedTensorToSparse'. The implementation (https://github.com/tensorflow/tensorflow/blob/f24faa153ad31a4b51578f8181d3aaab77a1ddeb/tensorflow/core/kernels/ragged_tensor_to_sparse_kernel.cc#L30) has an incomplete validation of the splits values: it does not check that they are in increasing order. The Tensorflow team has patched the issue in GitHub commit 1071f554dbd09f7e101324d366eec5f4fe5a3ece.
