Impact
The implementation of [
tf.raw ops.TensorSummaryV2](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/summary tensor op.cc#L33-L58) does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:python
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.cc
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.
