How to Fix CVE-2024-55587

To remediate this vulnerability, upgrade all affected Python libarchive dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

python-libarchive fixed: Latest secure release 
pip install python-libarchive>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show python-libarchive

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-55587, inspect your installed packages using pip:

pip show python-libarchive

Analyze the terminal output to locate any version of Python libarchive in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show python-libarchive command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Python libarchive, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

python-libarchive through 4.2.1 allows directory traversal (to create files) in extract in zip.py for ZipFile.extractall and ZipFile.extract.
