[LightDM] LightDM locking security bug

[Alexis Hunt]

Hi all,

I'm not sure if this is actually a bug or a misconfiguration on my system,
but I have discovered a major security vulnerability in screen locking
(dm-tool lock), and I would like some advice on how to proceed with it. I
didn't see a bug tracker or anything on the website and do not want to send
out what could be major security bug to a public mailing list.

My system is Debian testing and I use Xmonad as my WM.

Thank you very much!
Alexis Hunt
