    <p>
    Benjamin C. Wiley Sittler discovered a buffer overflow in Python's
    "repr()" function when handling UTF-32/UCS-4 encoded strings.
    </p>
  </description>
  <impact type="normal">
    <p>
    If a Python application processes attacker-supplied data with the
    "repr()" function, this could potentially lead to the execution of
    arbitrary code with the privileges of the affected application or a
    Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Python users should update to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.4.3-r4"</code>
  </resolution>
