Summary
TensorFlow vulnerable to null-dereference in `mlir::tfg::GraphDefImporter::ConvertNodeDef`
Details
Impact
When mlir::tfg::GraphDefImporter::ConvertNodeDef tries to convert NodeDefs without an op name, it crashes.
```cpp
Status GraphDefImporter::ConvertNodeDef(OpBuilder &builder, ConversionState &s,
const NodeDef &node) {
VLOG(4) << "Importing: " << node.name();
OperationState state(ConvertLocation(node), absl::StrCat("tfg.", node.op()));
// The GraphImporter does light shape inference, but here we will defer all of
// that to the shape inference pass.
const OpDef op_def;
const OpRegistrationData op_reg_data = nullptr;
if ((op_reg_data = registry_.LookUp(node.op()))) {
op_def = &op_reg_data->op_def;
} else {
auto it = function_op_defs_.find(node.op());
if (it == function_op_defs_.end())
return InvalidArgument("Unable to find OpDef for ", node.op());
op_def = it->second;
}
``node.op().empty()` cannot be empty.
Patches
We have patched the issue in GitHub commit a0f0b9a21c9270930457095092f558fbad4c03e5.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
