QFinch assessment
An attacker can cause denial of service in applications serving models using `tf.raw_ops.UnravelIndex` by triggering a division by 0:
Potential impact
An attacker can cause denial of service in applications serving models using tf.rawops.UnravelIndex by triggering a division by 0: The implementation does not check that the tensor subsumed by dims is not empty. Hence, if one element of dims is 0, the implementation does a division by 0.
