The remote Fedora host is missing a security update.
The update fixes memory leaks potentially leading to DoS (CVE-2008-3651 CVE-2008-3652). It also fixes problems with DPD and NAT-T support. 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.
