CVE-2021-37651: Out-of-bounds Write
(updated )
TensorFlow is an end-to-end open source platform for machine learning. The implementation for tf.raw_ops.FractionalAvgPoolGrad
can be tricked into accessing data outside of bounds of heap allocated buffers. The implementation 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.
