VLAI?
Summary
Crash due to erroneous `StatusOr` in TensorFlow
Details

Impact

A GraphDef from a TensorFlow SavedModel can be maliciously altered to cause a TensorFlow process to crash due to encountering a StatusOr value that is an error and forcibly extracting the value from it:

  if (op_reg_data->type_ctor != nullptr) {
    VLOG(3) << "AddNode: found type constructor for " << node_def.name();
    const auto ctor_type =
        full_type::SpecializeType(AttrSlice(node_def), op_reg_data->op_def);
    const FullTypeDef ctor_typedef = ctor_type.ValueOrDie();
    if (ctor_typedef.type_id() != TFT_UNSET) {
      *(node_def.mutable_experimental_type()) = ctor_typedef;
    }
  }

If ctor_type is an error status, ValueOrDie results in a crash.

Patches

We have patched the issue in GitHub commit 955059813cc325dc1db5e2daa6221271406d4439.

We have patched the issue in multiple GitHub commits and these will be included in TensorFlow 2.8.0 and TensorFlow 2.7.1, as both are affected.
