GHSA-5h2q-4hrp-v9rr

Summary: Django vulnerable to Improper Restriction of Operations within the Bounds of a Memory Buffer

Details: 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.
