python2.7 - security update

• CVE-2016-0772
  A vulnerability in smtplib allowing MITM attacker to perform a
  startTLS stripping attack. smtplib does not seem to raise an
  exception when the remote end (smtp server) is capable of
  negotiating starttls but fails to respond with 220 (ok) to an
  explicit call of SMTP.starttls(). This may allow a malicious
  MITM to perform a startTLS stripping attack if the client code
  does not explicitly check the response code for startTLS.
• CVE-2016-5636
  Issue #26171: Fix possible integer overflow and heap corruption
  in zipimporter.get_data().
• CVE-2016-5699
  Protocol injection can occur not only if an application sets a
  header based on user-supplied values, but also if the application
  ever tries to fetch a URL specified by an attacker (SSRF case) OR
  if the application ever accesses any malicious web server
  (redirection case).

For Debian 7 Wheezy, these problems have been fixed in version
2.7.3-6+deb7u3.

We recommend that you upgrade your python2.7 packages.
