  <synopsis>

    a local user to overwrite arbitrary files.

    <p>
    KDE is a feature-rich graphical desktop environment for Linux and
    Unix-like Operating Systems. DCOP is KDE's simple IPC/RPC mechanism.
    dcopidlng is a DCOP helper script.

    <p>
    Davide Madrisan has discovered that the dcopidlng script creates
    temporary files in a world-writable directory with predictable names.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create symbolic links in the temporary
    files directory, pointing to a valid file somewhere on the filesystem.
    When dcopidlng is executed, this would result in the file being
    overwritten with the rights of the user running the utility, which
    could be the root user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All kdelibs users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/kdelibs</code>
