How to Fix CVE-2024-25711

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

diffoscope fixed: 256 
pip install diffoscope>=256
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 diffoscope

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-25711, inspect your installed packages using pip:

pip show diffoscope

Analyze the terminal output to locate any version of Diffoscope in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 256), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Diffoscope, 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

diffoscope before 256 allows directory traversal via an embedded filename in a GPG file. Contents of any file, such as ../.ssh/id_rsa, may be disclosed to an attacker. This occurs because the value of the gpg --use-embedded-filenames option is trusted.
