Description

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.
