How to Fix CVE-2024-31636

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

lief fixed: 0.15.0 
pip install lief>=0.15.0
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 lief

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-31636, inspect your installed packages using pip:

pip show lief

Analyze the terminal output to locate any version of Lief in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.15.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-457: Use of Uninitialized Variable, where the code uses a variable that has not been initialized, leading to unpredictable or unintended results. In Lief, 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.
