[SECURITY] Fedora 30 Update: viewvc-1.1.28-1.fc30

ViewVC is a browser interface for CVS and Subversion version control repositories. It generates templatized HTML to present navigable directory, revision, and change log listings. It can display specific versions of files as well as diffs between those versions. Basically, ViewVC provides the bulk of the report-like functionality you expect out of your version control too l, but much more prettily than the average textual command-line program output.
