  <title>Python: Heap overflow in the included PCRE library</title>
  <synopsis>
    The "re" Python module is vulnerable to a heap overflow, possibly leading
    to the execution of arbitrary code.

  <affected>
    <package name="dev-lang/python" auto="yes" arch="*">
      <unaffected range="ge">2.3.5-r2</unaffected>

  <background>
    <p>
    Python is an interpreted, interactive, object-oriented,
    cross-platform programming language. The "re" Python module provides
    regular expression functions.
    </p>
  </background>
  <description>
    <p>
    The "re" Python module makes use of a private copy of libpcre
    which is subject to an integer overflow leading to a heap overflow (see
    GLSA 200508-17).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could target a Python-based web application (or SUID
    application) that would use untrusted data as regular expressions,
    potentially resulting in the execution of arbitrary code (or privilege
    escalation).
    </p>
  </impact>
  <workaround>
    <p>
    Python users that don't run any Python web application or SUID
    application (or that run one that wouldn't use untrusted inputs as
    regular expressions) are not affected by this issue.
    </p>
  </workaround>
  <resolution>
    <p>
    All Python users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.3.5-r2"</code>
  </resolution>
