Summary
LCDproc is a system that is used to display system information and other data on an LCD display (or any supported display device, including curses or text) The LCDproc version 4.0 and above uses a client-server protocol, allowing anyone with access to the LCDproc server to modify the displayed content. It is possible to cause the LCDproc server to crash and execute arbitrary code by sending the server a large buffer that will overflow its internal buffer.
