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:
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.
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.
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.
