    David Bloom reported two vulnerabilities where plug-ins (CVE-2007-6520)
    and Rich text editing (CVE-2007-6522) could be used to allow cross
    domain scripting. Alexander Klink (Cynops GmbH) discovered an issue
    with TLS certificates (CVE-2007-6521). Gynvael Coldwind reported that
    bitmaps might reveal random data from memory (CVE-2007-6524).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities, possibly leading
    to the execution of arbitrary code and cross domain scripting.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Opera users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-client/opera-9.25"</code>
  </resolution>
