:cve:`2021-25289`: Correct the fix for :cve:`2020-35654`
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The previous fix for :cve:`2020-35654` was insufficient due to incorrect
|
|
error checking in ``TiffDecode.c``.
|
|
|
|
:cve:`2021-25290`: Fix buffer overflow in ``TiffDecode.c``
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|

In ``TiffDecode.c``, there is a negative-offset ``memcpy`` with an invalid size.
|
|
|
|
:cve:`2021-25291`: Fix buffer overflow in ``TIFFReadRGBATile``
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
In ``TiffDecode.c``, invalid tile boundaries could lead to an out-of-bounds
|
|
read in ``TIFFReadRGBATile``.
|
|
|
|
:cve:`2021-25292`: Fix DOS attack
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The PDF parser has a catastrophic backtracking regex that could be used as a
|
|
DOS attack.
|
|
|
|

|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
