Solly, do you want to take this as an exercise and push novnc 0.5.1 update in EPEL6/7 ? It is updated in Rawhide so git merge should do.
Are there any backward compatibility issues?

The only potential issue would be the removal of two deprecated callback names (the underlying callbacks still exist, just the deprecated names for them were removed).  This would only affect people who had written a custom UI around the core noVNC javascript files (most users seem to just use onee of the two built-in HTML files), and were using the deprecated callbacks.  Note that those callback names had been deprecated for several versions before 0.4 (quite a long time)

Comment 4 Alan Pevec (Fedora) 2015-02-24 01:34:59 UTC
IMO fixing security issue trumps two (since 2012) deprecated callback names
but let's spell them out in the Bodhi update description.

In upstream 0.5 relnotes I see only this which looks related:
"NOTE: code which interfaces directly with noVNC may see minor breakage (e.g. custom UI elements, etc)."
