How to Fix CVE-2022-40923

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: Latest secure release 
pip install lief>=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 lief

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-40923, 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 the patched release), your application is affected.

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