Security Vulnerabilities fixed by 6.5.5 upgrade?

Several people have forwarded me this link:About Secunia Research | Flexera regarding security vulnerabilities in Domino which are fixed by upgrading to 6.5.5. Checking the fix list shows only a few odd fixes titled “fixed security vulnerability” and little details.

Has anyone upgraded from 6.5.4 or other to 6.5.5 purely for security reasons? Is the full version available yet?
