    <p>
    Takumi Asaki discovered that uim insufficiently checks environment
    variables. setuid/setgid applications linked against libuim could end
    up executing arbitrary code. This vulnerability only affects
    immodule-enabled Qt (if you build Qt 3.3.2 or later versions with
    USE="immqt" or USE="immqt-bc").
    </p>
  </description>
  <impact type="normal">
    <p>
    A malicious local user could exploit this vulnerability to execute
    arbitrary code with escalated privileges.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All uim users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-i18n/uim-0.4.5.1&quot;</code>
