Comment 5 Siddharth Sharma 2015-04-21 14:24:34 UTC 
Analysis
========

In the following code of ceph-deploy

keyring = '/etc/ceph/{cluster}.client.admin.keyring'.format(
        cluster=args.cluster)
    r = fetch_file(
        args=args,
        frompath=keyring,
        topath='{cluster}.client.admin.keyring'.format(
            cluster=args.cluster),
        _hosts=args.mon,
 )

It copies the keys without forcing the file permissions which by default leads to 777 which makes it world readable while copying it to all nodes or monitors
