    <p>
    Python 2.3 includes a copy of PCRE which is vulnerable to an integer
    overflow vulnerability, leading to a buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit the vulnerability by tricking a vulnerable
    Python application to compile a regular expressions, which could
    possibly lead to the execution of arbitrary code, a Denial of Service
    or the disclosure of sensitive information.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Python 2.3 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/python-2.3.6-r4&quot;</code>
  </resolution>
