Subject: CVE Request -- gnome-desktop3: Switching users dialog does not lock
 the screen for the original user account

Hello Josh, Steve, vendors,

   it has been reported that using of Gnome upon using of "Switch user" dialog, log in into a
new user account (user2), logout of new user account (user2) the desktop is returned to the
original user account (for user1) without prompting for a password. A locally proximate
attacker could use this flaw to access resources, which should be otherwise protected
by authentication.

Original report:

Upstream bug report:
[2] https://bugzilla.gnome.org/show_bug.cgi?id=648234

Could you allocate a CVE id for this?

Thanks && Regards, Jan.
