    python-django vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Applications using Django could be made to crash or expose sensitive
    information.
    
    Software Description:
    - python-django: High-level Python web development framework
    
    Details:
    
    It was discovered that Django incorrectly validated the scheme of a
    redirect target. If a user were tricked into opening a specially crafted
    URL, an attacker could possibly exploit this to conduct cross-site
    scripting (XSS) attacks. (CVE-2012-3442)
    
    It was discovered that Django incorrectly handled validating certain
    images. A remote attacker could use this flaw to cause the server to
    consume memory, leading to a denial of service. (CVE-2012-3443)
    
    Jeroen Dekkers discovered that Django incorrectly handled certain image
    dimensions. A remote attacker could use this flaw to cause the server to
    consume resources, leading to a denial of service. (CVE-2012-3444)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      python-django                   1.3.1-4ubuntu1.2
    
    Ubuntu 11.10:
      python-django                   1.3-2ubuntu1.3
    
    Ubuntu 11.04:
      python-django                   1.2.5-1ubuntu1.2
    
    Ubuntu 10.04 LTS:
      python-django                   1.1.1-2ubuntu1.5
    
    In general, a standard system update will make all the necessary changes.
