Does anyone know what these rkhunter log files indicate?

My computer froze and I had to unplug it so I ran rkhunter and found these warnings. Does anyone know what they indicate, please?

I'm not positive but I think this is just RKhunter scanning things and telling you that the properties have changed, it could be due to an update. Keep an eye on which files get updated so that when you run RKhunter and it tells you the properties have changed, you'll know it's ok.
