CVE-2025-47273

Description

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version 78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the permissions of the process running the Python code, which could escalate to remote code execution depending on the context. Version 78.1.1 fixes the issue.

Notes

mdeslaur

On focal and earlier, the python-pip package bundles python-setuptools binaries when built. After updating python-setuptools, a no-change rebuild of python-pip is required. On jammy and later, python-setuptools is bundled in the python-pip package and needs to be patched.
