…94300) Hi! I've been fuzzing different pytorch modules, and found a crash inside one of them. Specifically, I'm talking about a module for unpickling and a function called `Unpickler::readInstruction()`. Running this function with provided crash file results in a crash, which occurs while calling `auto dict = stack_.at(dict_pos).toGenericDict();` [unpickler.cpp:561](https://github.com/pytorch/pytorch/blob/0e94fbc0c8ab1572c88159c1a4c397b6eb824c01/torch/csrc/jit/serialization/unpickler.cpp#L561). The crash occurs, because the index `dict_pos` is out of bounds (which itself happens because the stack size is 0). Besides this pull-request, there is another one related to unpickler hardening: #84343 All tests were performed on this pytorch version: [abc54f9](https://github.com/pytorch/pytorch/tree/abc54f93145830b502400faa92bec86e05422fbd) ### How to reproduce 1. To reproduce the crash, use provided docker: [Dockerfile](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch) 2. Build the container: `docker build -t oss-sydr-fuzz-pytorch-reproduce .` 3. Copy crash file to the current directory: - [crash-042dff5e121580425d9d34d0f293918f3c9fbf1e.zip](https://github.com/pytorch/pytorch/files/10674361/crash-042dff5e121580425d9d34d0f293918f3c9fbf1e.zip) 4. Run the container: ``docker run --privileged --network host -v `pwd`:/homedir --rm -it oss-sydr-fuzz-pytorch-reproduce /bin/bash`` 5. And execute the binary: `/message_deserialize_sydr /homedir/crash-042dff5e121580425d9d34d0f293918f3c9fbf1e` After execution completes you will see this error message: ```txt terminate called after throwing an instance of 'std::out_of_range' what(): vector::_M_range_check: __n (which is 18446744073709551613) >= this->size() (which is 0) ``` And this stacktrace: ```asan erminate called after throwing an instance of 'std::out_of_range' what(): vector::_M_range_check: __n (which is 18446744073709551613) >= this->size() (which is 0) ==39== ERROR: libFuzzer: deadly signal #0 0x5d0df1 in __sanitizer_print_stack_trace /llvm-project/compiler-rt/lib/asan/asan_stack.cpp:87:3 #1 0x545727 in fuzzer::PrintStackTrace() /llvm-project/compiler-rt/lib/fuzzer/FuzzerUtil.cpp:210:5 #2 0x52b933 in fuzzer::Fuzzer::CrashCallback() /llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp:233:3 #3 0x7f9118e0341f (/lib/x86_64-linux-gnu/libpthread.so.0+0x1441f) #4 0x7f9118c2300a in raise (/lib/x86_64-linux-gnu/libc.so.6+0x4300a) #5 0x7f9118c02858 in abort (/lib/x86_64-linux-gnu/libc.so.6+0x22858) #6 0x7f9119040910 (/lib/x86_64-linux-gnu/libstdc++.so.6+0x9e910) #7 0x7f911904c38b (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa38b) #8 0x7f911904c3f6 in std::terminate() (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa3f6) #9 0x7f911904c6a8 in __cxa_throw (/lib/x86_64-linux-gnu/libstdc++.so.6+0xaa6a8) #10 0x7f91190433aa (/lib/x86_64-linux-gnu/libstdc++.so.6+0xa13aa) #11 0x63acdf in std::vector<c10::IValue, std::allocator<c10::IValue> >::_M_range_check(unsigned long) const /usr/bin/../lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/bits/stl_vector.h:1073:4 #12 0xce8f93e in std::vector<c10::IValue, std::allocator<c10::IValue> >::at(unsigned long) /usr/bin/../lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/bits/stl_vector.h:1094:2 #13 0xce8f93e in torch::jit::Unpickler::readInstruction() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:546:26 #14 0xce8d527 in torch::jit::Unpickler::run() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:235:27 #15 0xce8d1c2 in torch::jit::Unpickler::parse_ivalue() /pytorch_fuzz/torch/csrc/jit/serialization/unpickler.cpp:192:3 #16 0xcdf0792 in torch::jit::unpickle(std::function<unsigned long (char*, unsigned long)>, std::function<c10::StrongTypePtr (c10::QualifiedName const&)>, c10::ArrayRef<at::Tensor>, c10::Type::SingletonOrSharedTypePtr<c10::Type> (*)(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)) /pytorch_fuzz/torch/csrc/jit/serialization/pickle.cpp:127:20 #17 0xcdf104d in torch::jit::unpickle(char const*, unsigned long, std::function<c10::StrongTypePtr (c10::QualifiedName const&)>, c10::ArrayRef<at::Tensor>, c10::Type::SingletonOrSharedTypePtr<c10::Type> (*)(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)) /pytorch_fuzz/torch/csrc/jit/serialization/pickle.cpp:137:10 #18 0xe0532db in torch::distributed::rpc::ScriptRemoteCall::fromMessage(torch::distributed::rpc::Message const&) /pytorch_fuzz/torch/csrc/distributed/rpc/script_remote_call.cpp:74:16 #19 0xe0ffa10 in torch::distributed::rpc::deserializeRequest(torch::distributed::rpc::Message const&) /pytorch_fuzz/torch/csrc/distributed/rpc/utils.cpp:108:14 #20 0x602a41 in LLVMFuzzerTestOneInput /message_deserialize_fuzz.cc:192:27 #21 0x52ce61 in fuzzer::Fuzzer::ExecuteCallback(unsigned char const*, unsigned long) /llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp:611:15 #22 0x516d7c in fuzzer::RunOneTest(fuzzer::Fuzzer*, char const*, unsigned long) /llvm-project/compiler-rt/lib/fuzzer/FuzzerDriver.cpp:324:6 #23 0x51cacb in fuzzer::FuzzerDriver(int*, char***, int (*)(unsigned char const*, unsigned long)) /llvm-project/compiler-rt/lib/fuzzer/FuzzerDriver.cpp:860:9 #24 0x546062 in main /llvm-project/compiler-rt/lib/fuzzer/FuzzerMain.cpp:20:10 #25 0x7f9118c04082 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x24082) #26 0x51169d in _start (/message_deserialize_fuzz+0x51169d) NOTE: libFuzzer has rudimentary signal handlers.

Hi! I've been fuzzing different pytorch modules with with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch), and found a multiple crashes in torch::jit::load() function.

Hi! We've been fuzzing torchvision project with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz). We've found a heap buffer overflow error at `source_range_serialization.cpp:73` in pytorch project. The error occurs because there is not check in `deserialize_source` that `text_table_` size can be less than `fnameIndex`. To prevent the error the corresponding check must be located. torchvision version: 9d0a93eee90bf7c401b74ebf9c8be80346254f15 pytorch version: 0f1621d OS: Ubuntu 20.04 How to reproduce 1. Build docker from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/torchvision) and run the container: sudo docker build -t oss-sydr-fuzz-torchvision . sudo docker run --privileged --rm -v `pwd`:/fuzz -it oss-sydr-fuzz-torchvision /bin/bash 2. Run the target on this input: [serialization-crash.txt](https://github.com/pytorch/pytorch/files/11819901/serialization-crash.txt) /encode_png_fuzz serialization-crash.txt 3. You will see the following output: ================================================================= ==13==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x60200055a630 at pc 0x0000010197b7

### Description Hi! We've been fuzzing `pytorch` with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz) and found error of out of bounds access in `torch::jit` module. pytorch version: 18bcf62 The error occurs in `import_source.cpp:560` when we get the type from the `assign.rhs()`. `assign.rhs()` has `Maybe` type, as well as `assign.type()`, so one of them can be not presented. According to [grammar](https://github.com/pytorch/pytorch/blob/22f93852a2664b3dc29544ac6a36f1ec52c6caa2/torch/csrc/jit/frontend/tree_views.h), we can have `Assign` statement, which `lhs` will be `Subscript`, `rhs` will be empty (`Maybe` type with no subtrees) and `type` will be presented.

### Description Hi! We've been fuzzing `pytorch` with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz) and found error of out of bounds access in `torch::jit` module. pytorch version: 18bcf62 The error occurs in `import_source.cpp:560` when we get the type from the `assign.rhs()`. `assign.rhs()` has `Maybe` type, as well as `assign.type()`, so one of them can be not presented. According to [grammar](https://github.com/pytorch/pytorch/blob/22f93852a2664b3dc29544ac6a36f1ec52c6caa2/torch/csrc/jit/frontend/tree_views.h), we can have `Assign` statement, which `lhs` will be `Subscript`, `rhs` will be empty (`Maybe` type with no subtrees) and `type` will be presented. But in `import_source.cpp:560` we try to get `rhs` expression from the assignment with no check whether it is presented. This is example from the how to reproduce section from the testing input: ``` class Module(Module): __parameters__ = ["0", ] __buffers__ = [] __annotations__ = [] __annotations__["0"] : Tensor ``` When we parse the last statement of class definition, we set the type of `lhs` to `Subscript`, because the lookahead is `[` https://github.com/pytorch/pytorch/blob/76fb72e24a5a4a47ad1f50c5c94d5c0b7e703531/torch/csrc/jit/frontend/parser.cpp#L205-L207 Then in `parseAssignment` we get `maybeOp` and `type` depending on the next symbol (if it is `:`, we get only the type) https://github.com/pytorch/pytorch/blob/76fb72e24a5a4a47ad1f50c5c94d5c0b7e703531/torch/csrc/jit/frontend/parser.cpp#L437-L447 So after that, in `import_source.cpp:560`, parsing attributes, one of which is assignment with subscript type of `lhs`, we try to get type from `rhs` expression and out of bounds access occurs. To fix the error, we need to check whether the `rhs` or `type` are presented and get the type from corresponding expression. ### How to reproduce Build docker container from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch): ```bash $ sudo docker build -t oss-sydr-fuzz-pytorch ``` Run docker container: ```bash $ sudo docker run --rm --privileged -v `pwd`:/fuzz -it oss-sydr-fuzz-pytorch /bin/bash ``` Run the `load_fuzz` target on the [input.txt](https://github.com/pytorch/pytorch/files/12173962/input.txt) ```bash /load_fuzz input.txt ``` You will see the following output: ``` AddressSanitizer:DEADLYSIGNAL ================================================================= ==157==ERROR: AddressSanitizer: SEGV on unknown address (pc 0x00000c163764 bp 0x7ffee71d0070 sp 0x7ffee71d0050 T0) ==157==The signal is caused by a READ memory access. ==157==Hint: this fault was caused by a dereference of a high value address (see register values below).
