First published: Tue Jul 31 2012(Updated: )
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.
