    Michael A. Puls II discovered an unspecified flaw when launching
    external email or newsgroup clients (CVE-2007-5541). David Bloom
    discovered that when displaying frames from different websites, the
    same-origin policy is not correctly enforced (CVE-2007-5540).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could potentially exploit the first vulnerability to
    execute arbitrary code with the privileges of the user running Opera by
    enticing a user to visit a specially crafted URL. Note that this
    vulnerability requires an external e-mail or newsgroup client
    configured in Opera to be exploitable. The second vulnerability allows
    an attacker to execute arbitrary script code in a user's browser
    session in context of other sites or the theft of browser credentials.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time for all these
    vulnerabilities.
    </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-9.24"</code>
  </resolution>
