Discussion

Previous versions of software components that are not removed from the information system after updates have been installed may be exploited by adversaries. Some information technology products may remove older versions of software automatically from the information system.

Check Content

At the command line, run the following command:

# grep -i '^clean_requirements_on_remove' /etc/tdnf/tdnf.conf

Example result:

clean_requirements_on_remove=1

If "clean_requirements_on_remove" is not set to "true", "1", or "yes", this is a finding.

Fix Text

Navigate to and open:

/etc/tdnf/tdnf.conf

Add or update the following line:

clean_requirements_on_remove=1
