3.3.4 rear.x86_64 and rear.noarch

The .noarch version of the rear package in the ol7_x86_64_latest ULN channel has been superseded by a .x86_64 package for Oracle Linux 7 update 3.

To avoid the conflict you should exclude the rear.*.noarch package in your Yum configuration. See https://docs.oracle.com/cd/E52668_01/E54669/html/oln-dispkgup-uln.html in the Oracle Linux Administrator's Guide for Release 7 for more information on how to exclude packages. (Bug ID 25054687)
