# GHSA-4mqg-h5jf-j9m7: TorchServe Pre-Auth Remote Code Execution

## Affected packages

- PyPI `torchserve` >= 0.3.0, < 0.8.2 → fixed: 0.8.2

## Details

Impact Use of Open Source Library potentially exposed to RCE Issue: Use of a version of the SnakeYAML v1.31 open source library with multiple issues that potentially exposes the user to unsafe deserialization of Java objects. This could allow third parties to execute arbitrary code on the target system. This issue is present in versions 0.3.0 to 0.8.1. Mitigation: A pull request to address this issue has been merged - https://github.com/pytorch/serve/pull/2523. TorchServe release 0.8.2 includes this fix. Patches TorchServe release 0.8.2 includes fixes to address the previously listed issue: https://github.com/pytorch/serve/releases/tag/v0.8.2 Tags for upgraded DLC release User can use the following new image tags to pull DLCs that ship with patched TorchServe version 0.8.2: x86 GPU v1.9-pt-ec2-2.0.1-inf-gpu-py310 v1.8-pt-sagemaker-2.0.1-inf-gpu-py310 x86 CPU v1.8-pt-ec2-2.0.1-inf-cpu-py310 v1.7-pt-sagemaker-2.0.1-inf-cpu-py310 Graviton v1.7-pt-graviton-ec2-2.0.1-inf-cpu-py310 v1.5-pt-graviton-sagemaker-2.0.1-inf-cpu-py310 Neuron 1.13.1-neuron-py310-sdk2.13.2-ubuntu20.04 1.13.1-neuronx-py310-sdk2.13.2-ubuntu20.04 1.13.1-neuronx-py310-sdk2.13.2-ubuntu20.04 The full DLC image URI details can be found at: https://github.com/aws/deep-learning-containers/blob/master/availableimages.md#available-deep-learning-containers-images References https://github.com/pytorch/serve/pull/2523 https://github.com/pytorch/serve/releases/tag/v0.8.2 https://github.com/aws/deep-learning-containers/blob/master/availableimages.md#available-deep-learning-containers-images Credit We would like to thank Oligo Security for responsibly disclosing this issue and working with us on its resolution.
