    <p>The Python Cryptography Toolkit (PyCrypto) is a collection of both
      secure hash functions (such as SHA256 and RIPEMD160), and various
      encryption algorithms (AES, DES, RSA, ElGamal, etc.).

    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker, able to control the mode of operation in PyCrypto’s
      AES module, could possibly execute arbitrary code with the privileges of
      the process or cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All PyCrypto users should upgrade to the latest version:</p>
