| |
Hi. My brother has just discover a way to kill a linux box : * lauch an X11 app that use the DGA extension to take control of the video frame buffer. * switch to a console before the application take control of the screen * and see linux reboot instantly (in fact when the program access to the mapped buffer)
The application may write in a buffer that don't exist.
Contact directly Sylvain Vignaud <VIGNAUD.Sylvain@eulersff.com> to further information (until 11 june 16h GMT, after the account will be disabled). Maybe the problem can be avoided if the console is the fbcon.
