An attacker can cause a denial of service in applications serving models by calling `tf.raw_ops.UnravelIndex` in a way that triggers a division by 0, because the implementation does not check that the tensor subsumed by `dims` is not empty.","solution":"Patched in GitHub commit a776040a5e7ebf76eeb7eb923bf1ae417dd4d233.
