CVE-2022-21732: Memory exhaustion in Tensorflow
(updated )
The implementation of ThreadPoolHandle can be used to trigger a denial of service attack by allocating too much memory:
import tensorflow as tf
y = tf.raw_ops.ThreadPoolHandle(num_threads=0x60000000,display_name='tf')
This is because the num_threads argument is only checked to not be negative, but there is no upper bound on its value.
