CVE-2021-37643

Advisory

Tensorflow-rocm-enhanced 2.3.4 and 2.4.3 include a fix for CVE-2021-37643: If a user does not provide a valid padding value to 'tf.raw_ops.MatrixDiagPartOp', then the code triggers a null pointer dereference (if input is empty) or produces invalid behavior, ignoring all values after the first. The implementation (https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/linalg/matrix_diag_op.cc#L89) reads the first value from a tensor buffer without first checking that the tensor has values to read from. The Tensorflow team has patched the issue in GitHub commit 482da92095c4d48f8784b1f00dda4f81c28d2988.
