CVE-2021-37658

Advisory

Tensorflow-rocm 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37658: In affected versions an attacker can cause undefined behavior via binding a reference to null pointer in all operations of type 'tf.raw_ops.MatrixSetDiagV*'. The implementation (https://github.com/tensorflow/tensorflow/blob/84d053187cb80d975ef2b9684d4b61981bca0c41/tensorflow/core/kernels/linalg/matrix_diag_op.cc) has incomplete validation that the value of 'k' is a valid tensor. We have check that this value is either a scalar or a vector, but there is no check for the number of elements. If this is an empty tensor, then code that accesses the first element of the tensor is wrong. The Tensorflow team has patched the issue in GitHub commit ff8894044dfae5568ecbf2ed514c1a37dc394f1b.
