The data being read is now limited to only the necessary amount.

Fix OOB write with invalid tile extents
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:cve:`2026-42311`: Fix OOB write with invalid tile extents
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Pillow 12.1.1 addressed :cve:`2026-25990` by improving checks for tile extents to
prevent an OOB write from specially crafted PSD images in Pillow >= 10.3.0. However,
these checks did not consider integer overflow. This has been corrected.

Prevent PDF parsing trailer infinite loop
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:cve:`2026-42310`: Prevent PDF parsing trailer infinite loop
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When parsing a PDF, if a trailer refers to itself, or a more complex cyclic loop
exists, then an infinite loop occurs. Pillow now keeps a record of which trailers it
has already processed. PdfParser was added in Pillow 4.2.0.

Integer overflow when processing fonts
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:cve:`2026-42308`: Integer overflow when processing fonts
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If a font advances for each glyph by an exceeding large amount, when Pillow keeps track
of the current position, it may lead to an integer overflow. This has been fixed.

Heap buffer overflow with nested list coordinates
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:cve:`2026-42309`: Heap buffer overflow with nested list coordinates
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Passing nested lists as coordinates to APIs that accept coordinates such as
``ImagePath.Path``, :py:meth:`~PIL.ImageDraw.ImageDraw.polygon`
