    python-django regression
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    USN-2915-1 introduced a regression in Django.
    
    Software Description:
    - python-django: High-level Python web development framework
    
    Details:
    
    USN-2915-1 fixed vulnerabilities in Django. The upstream fix for
    CVE-2016-2512 introduced a regression for certain applications. This update
    fixes the problem by applying the complete upstream regression fix.
    
    Original advisory details:
    
     Mark Striemer discovered that Django incorrectly handled user-supplied
     redirect URLs containing basic authentication credentials. A remote
     attacker could possibly use this issue to perform a cross-site scripting
     attack or a malicious redirect. (CVE-2016-2512)
      Sjoerd Job Postmus discovered that Django incorrectly handled timing when
     doing password hashing operations. A remote attacker could possibly use
     this issue to perform user enumeration. (CVE-2016-2513)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      python-django                   1.7.9-1ubuntu5.4
      python3-django                  1.7.9-1ubuntu5.4
    
    Ubuntu 14.04 LTS:
      python-django                   1.6.1-2ubuntu0.14
    
    In general, a standard system update will make all the necessary changes.
