Jeroen Dekkers and others reported several vulnerabilities in Django, a Python Web framework. The Common Vulnerabilities and Exposures project defines the following issues: CVE-2012-3442Two 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-2012-3443The 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-2012-3444The 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.

Django is a high-level web application framework that loosely follows the model-view-controller design pattern.
