How to Fix CVE-2017-1000001

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

FedMsg fixed: 0.18.2 
pip install FedMsg>=0.18.2
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 FedMsg

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-1000001, inspect your installed packages using pip:

pip show FedMsg

Analyze the terminal output to locate any version of FedMsg in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.18.2), your application is affected.

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