Descriptions

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.

A path traversal vulnerability in the Python setuptools library allows attackers with limited system access to write files outside the intended temporary directory by manipulating package download URLs. This flaw bypasses basic filename sanitization and can lead to unauthorized overwrites of important system files, creating opportunities for further compromise. While it doesn't expose data or require user interaction, it poses a high integrity risk and is especially concerning in environments that rely on automated package handling or internal tooling built on setuptools.

An update for python-setuptools is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, Red Hat Enterprise Linux 8.6 Telecommunications Update Service, and Red Hat Enterprise Linux 8.6 Extended Update Support EXTENSION. Issues addressed include a traversal vulnerability.
