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.

Package : python-django
Date : August 23, 2012
Affected: 2011., Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in
python-django:

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 (CVE-2012-3442).

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 (memory consumption) by uploading an image file
(CVE-2012-3443).

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 (process or thread consumption)
via a large TIFF image (CVE-2012-3444).

The updated packages have been upgraded to the 1.3.3 version which
is not vulnerable to these issues.
