The remote Fedora host is missing one or more security updates.
New stable release, which includes security fix for msword-odf import filter. See also: http://www.calligra.org/news/calligra-2-5-released/ 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.
Update the affected calligra and / or calligra-l10n packages.
