Package : python-django
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-3442 CVE-2012-3443 CVE-2012-3444
Debian Bug : 683364
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.
