========
|
|
|
|
:cve:`2021-25289`: The previous fix for :cve:`2020-35654` was insufficient
|
|
due to incorrect error checking in ``TiffDecode.c``.
|
|
|
|
:cve:`2021-25290`: In ``TiffDecode.c``, there is a negative-offset ``memcpy``
|
|
with an invalid size.
|
|
|
|
:cve:`2021-25291`: In ``TiffDecode.c``, invalid tile boundaries could lead to
|
|
an out-of-bounds read in ``TIFFReadRGBATile``.
|
|
|
|
:cve:`2021-25292`: The PDF parser has a catastrophic backtracking regex
|
|
that could be used as a DOS attack.
|
|
|
|
:cve:`2021-25293`: There is an out-of-bounds read in ``SgiRleDecode.c``,
|
|
since Pillow 4.3.0.
