COMMAND Microimages X [MIX] SYSTEMS AFFECTED Microimages X Server for Win PROBLEM Mike Wilson found following. Microimages has one nice X server for Windows, which allow you to wun Windows 95/98 and to work Graphicaly with some *NIX based system, for example if you have SunOS and you export your DISPLAY to your host where you're running Windows95/98 with MIX server, and all you run on your Sun will be graphicaly come to my windows X server. What is the vulnerable. If you know someone is using that X server, you just type: export DISPLAY=hishost.com:0.0 xterm ( then wait about 10 seconds and hit Ctrl-C ) It will kill MIX server on remote Machine. Where is the bug? MIX kills automatically when someone stop the process locally from the *NIX based system, not killing the process from the X server by closing the windows. That's It. SOLUTION You will find this has to do with the option "close after last process exits" in preferences. When you open the xterm and then close it, it follows it's settings and exits. It is normal behavior. Now that person having thier X server accessable by you is another story.
