Summary

It was discovered that a world-readable log file belonging to Candlepin component of Red Hat Satellite 6.4 leaked the credentials of the Candlepin database. A malicious user with local access to a Satellite host can use those credentials to modify the database and prevent Satellite from fetching package updates, thus preventing all Satellite hosts from accessing those updates.
