    Moritz Jodeit reported an off-by-one error in the
    SSL_get_shared_ciphers() function, resulting from an incomplete fix of
    CVE-2006-3738. A flaw has also been reported in the
    BN_from_montgomery() function in crypto/bn/bn_mont.c when performing
    Montgomery multiplication.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker sending a specially crafted packet to an application
    relying on OpenSSL could possibly execute arbitrary code with the
    privileges of the user running the application. A local attacker could
    perform a side channel attack to retrieve the RSA private keys.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All OpenSSL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/openssl-0.9.8e-r3"</code>
  </resolution>
