The remote Fedora host is missing one or more security updates.
Update to the new upstream Firefox 3.0.7 / XULRunner 184.108.40.206 fixing multiple security issues: http://www.mozilla.org/security/known- vulnerabilities/firefox30.html#firefox3.0.7 This update also contains new builds of all applications depending on Gecko libraries, built against the new version. Note: after the updated packages are installed, Firefox must be restarted for the update to take effect. 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.
