    Jeroen Dekkers and others reported several vulnerabilities in Django,
    a Python Web framework. The Common Vulnerabilities and Exposures
    project defines the following issues:
    
    CVE-2012-3442
    
        Two functions do not validate the scheme of a redirect target,
        which might allow remote attackers to conduct cross-site scripting
        (XSS) attacks via a data: URL.
    
    CVE-2012-3443
    
        The ImageField class completely decompresses image data during image
        validation, which allows remote attackers to cause a denial of service
        (memory consumption) by uploading an image file.
    
    CVE-2012-3444
    
        The get_image_dimensions function in the image-handling functionality
        uses a constant chunk size in all attempts to determine dimensions,
        which allows remote attackers to cause a denial of service (process
        or thread consumption) via a large TIFF image.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 1.2.3-3+squeeze3.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.4.1-1.
    
    We recommend that you upgrade your python-django packages.
