[SECURITY] Fedora 27 Update: plexus-archiver-3.4-4.fc27

The Plexus project seeks to create end-to-end developer tools for writing applications. At the core is the container, which can be embedded or for a full scale application server. There are many reusable components for hibernate, form processing, jndi, i18n, velocity, etc. Plexus also includes an application server which is like a J2EE application server, without all the baggage.
