What is CVE-2023-47248?

A deserialization vulnerability exists in PyArrow, specifically in its handling of Arrow IPC, Feather, and Parquet data. This flaw enables potential adversaries to execute arbitrary code during data reading processes when using vulnerable versions of PyArrow (0.14.0 to 14.0.0) with untrusted input sources. Users are strongly urged to update to PyArrow version 14.0.1 or later. For those unable to upgrade immediately, a hotfix is available through a separate package to mitigate the risk on older versions.

Affected Version(s)

PyArrow 0.14.0 <= 14.0.0

PyArrow 0.14.0 <= 14.0.0

Exploit Proof of Concept (PoC)
