Upgrade pyarrow to version 0.15.1 or higher.
Overview
pyarrow is a Python API for functionality provided by the Arrow C++ libraries, along with tools for Arrow integration and interoperability with pandas, NumPy, and other software in the Python ecosystem.
Affected versions of this package are vulnerable to Use of Uninitialized Variable. It was discovered that the C++ implementation (which underlies the R, Python and Ruby implementations) of Apache Arrow has an uninitialized memory bug when building arrays with null values in some cases. This can lead to uninitialized memory being unintentionally shared if Arrow Arrays are transmitted over the wire (for instance with Flight) or persisted in the streaming IPC and file formats.
