The remote Fedora host is missing a security update.
Updated to upstream version 2.0.21. See : - http://symfony.com/blog/security-release-symfony-2-0-20- and-2-1-5-released - http://symfony.com/blog/symfony-2-0-21-and-2-1-5-relea sed Changelogs : - 2.0.20 > 2.0.21: https://github.com/symfony/symfony/compare/v2.0.20...v2. 0.21 - 2.0.19 > 2.0.20: https://github.com/symfony/symfony/compare/v2.0.19...v 2.0.20 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.
