update to 1.6.5 fixing CVE-2014-1418

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.

Multiple vulnerabilities has been discovered and corrected in python-django :

Django 1.4 before 1.4.13, 1.5 before 1.5.8, 1.6 before 1.6.5, and 1.7 before 1.7b4 does not properly include the (1) Vary: Cookie or (2) Cache-Control header in responses, which allows remote attackers to obtain sensitive information or poison the cache via a request from certain browsers (CVE-2014-1418).

The django.util.http.is_safe_url function in Django 1.4 before 1.4.13, 1.5 before 1.5.8, 1.6 before 1.6.5, and 1.7 before 1.7b4 does not properly validate URLs, which allows remote attackers to conduct open redirect attacks via a malformed URL, as demonstrated by http:\djangoproject.com. (CVE-2014-3730).

The django.core.urlresolvers.reverse function in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 allows remote attackers to import and execute arbitrary Python modules by leveraging a view that constructs URLs using user input and a dotted Python path. (CVE-2014-0472).

The caching framework in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 reuses a cached CSRF token for all anonymous users, which allows remote attackers to bypass CSRF protections by reading the CSRF cookie for anonymous users (CVE-2014-0473).

The (1) FilePathField, (2) GenericIPAddressField, and (3) IPAddressField model field classes in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 do not properly perform type conversion, which allows remote attackers to have unspecified impact and vectors, related to MySQL typecasting.
(CVE-2014-0474).

The updated packages have been patched to correct these issues.

Stephen Stewart, Michael Nelson, Natalia Bidart and James Westby discovered that Django improperly removed Vary and Cache-Control headers from HTTP responses when replying to a request from an Internet Explorer or Chrome Frame client. An attacker may use this to retrieve private data or poison caches. This update removes workarounds for bugs in Internet Explorer 6 and 7. (CVE-2014-1418)

Peter Kuma and Gavin Wahl discovered that Django did not correctly validate some malformed URLs, which are accepted by some browsers. An attacker may use this to cause unexpected redirects. An update has been provided for 12.04 LTS, 12.10, 13.10, and 14.04 LTS; this issue remains unfixed for 10.04 LTS as no 'is_safe_url()' functionality existed in this version.
