How to Fix CVE-2014-3555

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

neutron fixed: 2013.2.4 
pip install neutron>=2013.2.4
neutron fixed: 2014.1.2 
pip install neutron>=2014.1.2
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 neutron

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2014-3555, inspect your installed packages using pip:

pip show neutron

Analyze the terminal output to locate any version of Neutron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2013.2.4), your application is affected.

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