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The .noarch version of the rear package in the ol7_x86_64_latest ULN channel has been superseded by a .x86_64 package for Oracle Linux 7 update 3.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 Oracle® Linux 7: Administrator's Guide for more information on how to exclude packages. (Bug ID 25054687)
