lief fixed: 0.17.2 
pip install lief>=0.17.2
lief fixed: 0.17.2 
Upgrade lief to 0.17.2
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-2025-15504, 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 0.17.2), 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-404: Improper Resource Shutdown or Release, where the product does not release or incorrectly releases a resource before it is made available for re-use. 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.

Source Advisory Statement

A security flaw has been discovered in lief-project LIEF up to 0.17.1. Affected by this issue is the function Parser::parse_binary of the file src/ELF/Parser.tcc of the component ELF Binary Parser. The manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.17.2 can resolve this issue. The patch is identified as 81bd5d7ea0c390563f1c4c017c9019d154802978. It is recommended to upgrade the affected component.
