Description Cedric Buissart 2016-05-27 17:21:06 UTC

/var/lib/rhsm/cache/entitlement_status.json and /var/lib/rhsm/facts/facts.json are world readable but contain sensitive information (Red Hat Contract number and hardware serial number, sufficient to authenticate again Red Hat and hardware vendor support) can could be used by an attacker to perform a social engineering attack.
