Overview
nvidia-pytriton is a PyTriton - Flask/FastAPI-like interface to simplify Triton's deployment in Python environments.
Affected versions of this package are vulnerable to Buffer Access with Incorrect Length Value via the MessageQueueShm class in the bundled Python backend. An attacker could cause an out-of-bounds write by sending a specially crafted request, leading to information disclosure, denial of service, or remote code execution, through corruption of existing data structures within the backend's shared memory.
Note: This vulnerability is only exploitable when using the default bundled Python backend /pytriton/tritonserver/backends/python/libtriton_python.so.
Workaround
It is possible to update the Python backend to a patched version independently of PyTriton; See Triton Inference Server Backend and Building binaries from source.
