Description of problem:
This denial happened right after or during update. I was not using or configring CUPS at the time. 
SELinux is preventing cupsd from 'read' accesses on the file hosts.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that cupsd should be allowed read access on the hosts file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'cupsd' --raw | audit2allow -M my-cupsd
# semodule -X 300 -i my-cupsd.pp
