    Subject: UnixWare 7.1.1 Open UNIX 8.0.0 UnixWare 7.1.3 : REVISED: Lax permissions on /dev/X
    Advisory number: CSSA-2003-SCO.4.1
    Issue date: 2003 March 10
    Cross reference: CSSA-2003-SCO.4
    ______________________________________________________________________________

    1. Problem Description

            The /dev/X directory is world readable and writable, and
            the files in it are also world readable and writable.
            Denial-of-Service attacks are possible, as well as possible
            data hijacking. The X server sets these permissions when
            it starts up, so there is no workaround for this issue.

            This update fixes an install problem on Open UNIX 8 and
            UnixWare 7.1.3.

    2. Vulnerable Supported Versions

            System Binaries
            ----------------------------------------------------------------------

            Open UNIX 8.0.0 Standard X Distribution
            UnixWare 7.1.3 Standard X Distribution

    3. Solution

            The proper solution is to install the latest packages.
