Details on the issue are not confirmed by the reporter after several attempts
and this does like a non-issue. More reprodicibly reports are from SUSE in
https://bugzilla.novell.com/show_bug.cgi?id=1074318#c5 claiming this might be
a duplicate of CVE-2017-9935. Unless the reporter provides more details on
upstream report go and consider this as non-issue.
