The remote Fedora host is missing one or more security updates.
Updated WebKit packages are available which fix two security vulnerabilities: CVE-2008-1010 (Arbitrary code execution) and CVE-2008-1011 (Cross-Site Scripting). 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 WebKit, kazehakase and / or midori packages.
