The "Say something to Siri allows you to unlock the phone" bug has been fixed almsot every update in various forms since iOS 7.
My colleague was an Apple fan and didn't believe me when I was telling him about them. He said something like "Call Mum" in the same room as his (locked, default settings) iPhone, and it unlocked, silently dialled the caller, and just sat there transmitting what we were saying to his mother.
It also allowed, if you swiped/pressed the right parts, you to get into apps that were supposed to be "locked".
So this is not only a fix to a fix, but a fix to a fix to a fix to a fix to a fix, all hitting the exact same class of bugs - that Siri just unlocks your phone and tries to hide your stuff rather than runs in a actual separate space when your phone is locked.
Biting the hand that feeds IT
