CVE-2021-37651

Advisory

Tensorflow-rocm 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37651: In affected versions the implementation for 'tf.raw_ops.FractionalAvgPoolGrad' can be tricked into accessing data outside of bounds of heap allocated buffers. The implementation (https://github.com/tensorflow/tensorflow/blob/f24faa153ad31a4b51578f8181d3aaab77a1ddeb/tensorflow/core/kernels/fractional_avg_pool_op.cc#L205) does not validate that the input tensor is non-empty. Thus, code constructs an empty 'EigenDoubleMatrixMap' and then accesses this buffer with indices that are outside of the empty area. The Tensorflow team has patched the issue in GitHub commit 0f931751fb20f565c4e94aa6df58d54a003cdb30.
