Description Martin Prpič 2015-11-23 12:07:08 UTC

LXDM before 0.5.2 did not start X server with -auth parameter.
Therefore any user able to connect to it (typically all local users)
would have their X connections accepted.  The issue was fixed via:

Additional information is available in bug 1268900.

This was already fixed in all Fedora versions via bug 1268900.
