Bug description:
Binary package hint: sugar

Sugar-Emulator uses the '-ac' flag in the Xephyr command line, with turns off access control. 

This means that anyone on the network can attach to the display/keyboard/mouse and interfer with the operation of Sugar (such as running xeyes, which goes full screen and can not be cancelled!).

With Xephyr on display :1
