...otally certain how to exploit this, and it may not be exploitable. But I''d bet money that it is exploitable and I figured you''d like to know before BUGTRAQ. Anyways, now for the explanation. Zoid moved my vga_init() call, which was in the .c file with the linux main(), into the svgalib .c file, apparently. While this is more "clean," (esp. considering my stupd inclusion of vga_init() { } into the X-specific .c files).

...suid. In general, there is absolutely no reason for programs that are supposed to be run only by root to be suid to root! If your installation has SuperProbe suid to root, remove the suid bit from it. There is no need to users to run this program. While you are at it, seriously consider removing SVGAlib programs from your system Alex
