Heap-buffer-overflow during tensor unpickling
Labels: module: serialization, triaged

### 🐛 Describe the bug

Hi! We've been fuzzing PyTorch project with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz).
We've found a heap buffer overflow error at `conv_serialization.h:179` in jit module.

The out-of-buffer read occurs during traversal of tensor' input data. Tensor `accessor` computes indexes for its inner data according to the tensor `sizes` and `strides` values. `sizes` and `strides` are set for a tensor during it's deserialization from a raw binary data. The comments in code for a corresponding PyTorch API function (`set_sizes_and_strides`) says, that this function does not check if the requested sizes/strides are in bounds for the storage that is allocated and this is the responsibility of the caller.

PyTorch version: cdf7f3e78032a17600f701e9153e9bb49fad8ce7

OS: Ubuntu 20.04

How to reproduce

1. Build docker from [here](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch) and run the container:

        sudo docker build -t oss-sydr-fuzz-pytorch .
        sudo docker run --privileged --rm -v `pwd`:/fuzz -it oss-sydr-fuzz-pytorch /bin/bash

2. Run the target on this input: [crash.txt](https://github.com/pytorch/pytorch/files/12686267/crash.txt)

        /load_afl crash.txt

3. You will see the following output:
