TODO
^^^^
Ensure JpegImagePlugin stops at the end of a truncated file
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

TODO
``JpegImagePlugin`` may append an EOF marker to the end of a truncated file, so that
the last segment of the data will still be processed by the decoder.

If the EOF marker is not detected as such however, this could lead to an infinite
loop where ``JpegImagePlugin`` keeps trying to end the file.

Remove consecutive duplicate tiles that only differ by their offset
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To prevent attempts to slow down loading times for images, if an image has consecutive
duplicate tiles that only differ by their offset, only load the last tile. Credit to
Google's `OSS-Fuzz`_ project for finding this issue.

Fixed ImagePath.Path array handling
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

CWE-126 and CWE-665 were found when initializing ``ImagePath.Path``.
