PyArrow security vulnerability when reading IPC Streaming or Parquet files.

[anjakefala]

Hey guys,

Since some of you either use VisiData to read Arrow and Parquet data, or use PyArrow in your lives, I wanted to let you know about an existing security vulnerability in PyArrow.

Deserialization of untrusted data in IPC and Parquet readers in PyArrow versions 0.14.0 to 14.0.0 allows arbitrary code execution. An application is vulnerable if it reads Arrow IPC, Feather or Parquet data from untrusted sources (for example user-supplied input files).

This vulnerability only affects PyArrow, not other Apache Arrow implementations or bindings.

It is recommended that users of PyArrow upgrade to 14.0.1. Similarly, it is recommended that downstream libraries upgrade their dependency requirements to PyArrow 14.0.1 or later. PyPI packages are already available, and so are conda-forge: https://anaconda.org/conda-forge/pyarrow

If it is not possible to upgrade, maintainers provide a separate package pyarrow-hotfix that disables the vulnerability on older PyArrow versions. See https://pypi.org/project/pyarrow-hotfix/ for instructions.

Python 3.7 only supports up until 12.0.1. So on VisiData's end, we bumped the minimum dependency version for pyarrow on 3.8+ and install pyarrow_hotfix for 3.7: 23de62c
