Statement:

This flaw is out of support scope for Red Hat Enterprise Linux 6 and 7. It does not affect Red Hat Enterprise Linux 8 because the ImageMagick package is not shipped. To learn more about Red Hat Enterprise Linux support scope, please see https://access.redhat.com/support/policy/updates/errata/ .
