    <p>
    Chris Evans reported multiple integer overflows in the expandtabs
    method, as implemented by (1) the string_expandtabs function in
    Objects/stringobject.c and (2) the unicode_expandtabs function in
    Objects/unicodeobject.c.

  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities in Python
    applications or daemons that pass user-controlled input to vulnerable
    functions. The security impact is currently unknown but may include the
    execution of arbitrary code or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Python 2.5 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.5.4-r2"</code>
    <p>
    All Python 2.4 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.4.6"</code>
  </resolution>
