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.
