CVE-2022-23590: Crash due to erroneous `StatusOr` in TensorFlow
(updated )
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.
