python-django - security update

Several vulnerabilities were discovered in Django, a high-level Python
web development framework. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2014-0472
  Benjamin Bach discovered that Django incorrectly handled dotted
  Python paths when using the reverse() URL resolver function. An
  attacker able to request a specially crafted view from a Django
  application could use this issue to cause Django to import arbitrary
  modules from the Python path, resulting in possible code execution.
• CVE-2014-0473
  Paul McMillan discovered that Django incorrectly cached certain
  pages that contained CSRF cookies. A remote attacker could use this
  flaw to acquire the CSRF token of a different user and bypass
  intended CSRF protections in a Django application.
• CVE-2014-0474
  Michael Koziarski discovered that certain Django model field classes
  did not properly perform type conversion on their arguments, which
  allows remote attackers to obtain unexpected results.
• CVE-2014-1418
  Michael Nelson, Natalia Bidart and James Westby discovered that
  cached data in Django could be served to a different session, or to
  a user with no session at all. An attacker may use this to retrieve
  private data or poison caches.
• CVE-2014-3730
  Peter Kuma and Gavin Wahl discovered that Django incorrectly
  validated certain malformed URLs from user input. An attacker may
  use this to cause unexpected redirects.
