    python-django regression
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 13.10
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    USN-2169-1 introduced a regression in Django.
    
    Software Description:
    - python-django: High-level Python web development framework
    
    Details:
    
    USN-2169-1 fixed vulnerabilities in Django. The upstream security patch
    for CVE-2014-0472 introduced a regression for certain applications. This
    update fixes the problem.
    
    Original advisory details:
    
     Benjamin Bach discovered that Django incorrectly handled dotted Python
     paths when using the reverse() function. An attacker could use this issue
     to cause Django to import arbitrary modules from the Python path, resulting
     in possible code execution. (CVE-2014-0472)
      Paul McMillan discovered that Django incorrectly cached certain pages that
     contained CSRF cookies. An attacker could possibly use this flaw to obtain
     a valid cookie and perform attacks which bypass the CSRF restrictions.
     (CVE-2014-0473)
      Michael Koziarski discovered that Django did not always perform explicit
     conversion of certain fields when using a MySQL database. An attacker
     could possibly use this issue to obtain unexpected results. (CVE-2014-0474)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      python-django                   1.6.1-2ubuntu0.2
    
    Ubuntu 13.10:
      python-django                   1.5.4-1ubuntu1.2
    
    Ubuntu 12.10:
      python-django                   1.4.1-2ubuntu0.6
    
    Ubuntu 12.04 LTS:
      python-django                   1.3.1-4ubuntu1.10
    
    Ubuntu 10.04 LTS:
      python-django                   1.1.1-2ubuntu1.11
    
    In general, a standard system update will make all the necessary changes.
