Status Candidate

Overview

The (1) django.http.HttpResponseRedirect and (2) django.http.HttpResponsePermanentRedirect classes in Django before 1.3.2 and 1.4.x before 1.4.1 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.

Ubuntu Security Notice 1560-1 - 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. 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. Various other issues were also addressed.

Mandriva Linux Security Advisory 2012-143

Mandriva Linux Security Advisory 2012-143 - Multiple vulnerabilities has been discovered and corrected in python-django. The django.http.HttpResponsePermanentRedirect classes in Django before 1.3.2 and 1.4.x before 1.4.1 do not validate the scheme of a redirect target, which might allow remote attackers to conduct cross-site scripting attacks via a data: URL. The django.forms.ImageField class in the form system in Django before 1.3.2 and 1.4.x before 1.4.1 completely decompresses image data during image validation, which allows remote attackers to cause a denial of service by uploading an image file. The get_image_dimensions function in the image-handling functionality in Django before 1.3.2 and 1.4.x before 1.4.1 uses a constant chunk size in all attempts to determine dimensions, which allows remote attackers to cause a denial of service via a large TIFF image. The updated packages have been upgraded to the 1.3.3 version which is not vulnerable to these issues.
