I know that for Red Hat the pre-disclosure was useful. During analysis, like SUSE, we rated it as having a security impact of Moderate (https://access.redhat.com/security/updates/classification); and not highly impacting that required expedited preparation of packages for the embargo date. Additional information is contained within the bugzilla linked off our CVE page (https://bugzilla.redhat.com/show_bug.cgi?id=1490344). We look forward to working with you again in the future. Regards, Cliff -- Senior Engineering Manager Red Hat Product Security
