If you are concerned about the security of a system, then you should understand how the vendor manages updates.
The reason most people would choose RHEL/Centos/Suse over Debian/Ubuntu/Arch/Gentoo is that the former publish distributions around a collection of software with a well-defined upgrade timetable/path. RedHat and co would not stay in business very long if they were selling vulnerable software, so in order to ensure the continued security of their distribution while not undermining their customers efforts, they will backport security fixes from upstream releases into the version they include in their distribution(s).
Yes, you can uninstall the RPM and either link to an unofficial repo with the latest versions of software, or compile from source yourself, but in both cases the software is no longer covered by your support agreement with RedHat, and in the latter case requires regular effort to ensure the software is up to date.
