    Package        : xaos
    Vulnerability  : improper setuid-root execution
    Problem-Type   : local
    Debian-specific: no
    
    XaoS, a program for displaying fractal images, is installed setuid
    root on certain architectures in order to use svgalib, which requires
    access to the video hardware.  However, it is not designed for secure
    setuid execution, and can be exploited to gain root privileges.
    
    In these updated packages, the setuid bit has been removed from the
    xaos binary.  Users who require the svgalib functionality should grant
    these privileges only to a trusted group.
    
    This vulnerability is exploitable in version 3.0-18 (potato) on i386
    and alpha architectures, and in version 3.0-23 (woody) on the i386
    architecture only.
    
    For the stable distribution (woody) this problem has been fixed in
    version 3.0-23woody1.
    
    For the old stable distribution (potato) this problem has been fixed
    in version 3.0-18potato1.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 3.1r-4.
    
    We recommend that you update your xaos package.
