Due to lack of validation in…","summary":"CVE-2021-29581 affects TensorFlow's `tf.raw_ops.CTCBeamSearchDecoder`, which lacks input validation. The implementation fails to detect an empty input tensor and reads from a null buffer, so an attacker can trigger a denial of service through segmentation faults.","solution":"The fix will be included in TensorFlow 2.5.0. The commit will also be cherrypicked to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow
