Summary
Out of bounds read in Tensorflow
Details

Impact

TensorFlow's type inference can cause a heap OOB read as the bounds checking is done in a DCHECK (which is a no-op during production):

if (node_t.type_id() != TFT_UNSET) {
  int ix = input_idx[i];
  DCHECK(ix < node_t.args_size())
      << "input " << i << " should have an output " << ix
      << " but instead only has " << node_t.args_size()
      << " outputs: " << node_t.DebugString();
  input_types.emplace_back(node_t.args(ix));
  // ...
}

An attacker can control input_idx such that ix would be larger than the number of values in node_t.args.

Patches

We have patched the issue in GitHub commit c99d98cd189839dcf51aee94e7437b54b31f8abd.

The fix will be included in TensorFlow 2.8.0. This is the only affected version.
