Summary
Missing validation causes `TensorSummaryV2` to crash
Details
Impact
The implementation of tf.raw_ops.TensorSummaryV2 does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:
import numpy as np
import tensorflow as tf
tf.raw_ops.TensorSummaryV2(
tag=np.array('test'),
tensor=np.array(3),
serialized_summary_metadata=tf.io.encode_base64(np.empty((0))))
The code assumes axis is a scalar but there is no validation for this.
const Tensor& serialized_summary_metadata_tensor = c->input(2);
// ...
ParseFromTString(serialized_summary_metadata_tensor.scalar<tstring>()(),
v->mutable_metadata());
Patches
We have patched the issue in GitHub commit 290bb05c80c327ed74fae1d089f1001b1e2a4ef7.
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
