Hi Hanno,
The detail of your report was good quality and I'm sure appreciated by
everyone who needed to review it. 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 (;
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

We look forward to working with you again in the future.
