The remote Fedora host is missing a security update.
Update to new version 2.4.16. This update fixed various bugs as well as few security issues. For full changelog, see http://www.apache.org/dist/httpd/CHANGES_2.4.16 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
