In affected versions due to incomplete…","summary":"TensorFlow's `tf.raw_ops.QuantizeV2` performs incomplete validation, so an attacker can trigger undefined behavior by binding a reference to a null pointer, or read data outside heap-allocated arrays. The implementation does not check that `min_range` and `max_range` have the same non-zero number of elements, nor that `axis` is in range for the rank of `input` and the range lengths match the `axis` dimension.","solution":"Patched in GitHub commit 6da6620efad397c85493b8f8667b821403516708.
