It delayed telling the world to allow time for OS providers to apply fixes.
This is now standard and the delays are defined...


Linux, Windows and Mac got notified early November. FreeBSD just before
Christmas with no time to cope. All other BSDs and OpenSolaris found out on
release :(.

But this embargo was super long. Intel found out in June...


but it looks like in this case it leaked early. Similar bugs affect ARM,
AMD and PowerPC but nothing from them either. IBM won't tell the world (it
will tell customers, but I am not a customer) if and how it affects Z.
