    setuptools: Windows path escape via namespace_packages.txt during legacy wheel installation Description

    ### Summary On Windows, attacker-controlled content in a wheel's `.dist-info/namespace_packages.txt` can cause setuptools' legacy wheel installation path to create an `__init__.py` outside the requested `destination_eggdir`. The attacker can influence the destination path, but not the contents of the created file. ### Details Tested setuptools commit: `6ead555c5fb29bc57fe6105b1bffc163f56fd558` Relevant source: `setuptools/wheel.py` SHA-256: `359b7e0d5dd8c3135653abe08a8ed5dc0352eadfd7df22cb5e2b5303b7c3cafd` The relevant call path is: `Wheel(wheel_path).install_as_egg(destination)` → `_install_as_egg` → `_convert_metadata` → `_fix_na

    setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

    setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.

    setuptools has a path traversal vulnerability in PackageIndex.download that leads to Arbitrary File Write

    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.

  4. CVE-2024-6345

    High · CVSS 8.8EPSS 1.94%Fix available

    Remote Code Execution in pypa/setuptools

    A vulnerability in the package_index module of pypa/setuptools versions up to 69.1.1 allows for remote code execution via its download functions. These functions, which are used to download packages from URLs provided by users or retrieved from package index servers, are susceptible to code injection. If these functions are exposed to user-controlled inputs, such as package URLs, they can execute arbitrary commands on the system. The issue is fixed in version 70.0.

    CVE-2013-1633

    easy_install in setuptools before 0.7 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to the default use of the product.
