      DCOPServer Temporary Filename Vulnerability
    ------------------------------------------------------------------------

    SUMMARY

    The Debian project was alerted that KDE's DCOPServer creates temporary
    files in an insecure manner. Since the temporary files are used for
    authentication related purposes this can potentially allow a local
    attacker to compromise the account of any user that runs a KDE
    application.

    DETAILS

    Vulnerable Systems:
     * KDE 3.2.x up to KDE 3.2.3 inclusive

    CVE Information:
     <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0690>
    CAN-2004-0690

    Impact:
    KDE's DCOPServer creates temporary files in an insecure manner. Since the
    temporary files are used for authentication related purposes this can
    potentially allow a local attacker to compromise the account of any user
    that runs a KDE application.

    Solution:
    Source code patches have been made available which fix these
    vulnerabilities. Contact your OS vendor / binary package provider for
    information about how to obtain updated binary packages.
