  <description>
    <p>
    Opera makes use of OpenSSL, which fails to correctly verify PKCS #1
    v1.5 RSA signatures signed by a key with exponent 3. Some CAs in
    Opera's list of trusted signers are using root certificates with
    exponent 3.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could forge certificates which will appear valid and signed
    by a trusted CA.
    </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 &quot;&gt;=www-client/opera-9.02&quot;</code>
  </resolution>
