@ -69,6 +69,27 @@ There has been a longstanding warning that the defaults of ``Image.frombuffer``
may change in the future for the "raw" decoder. The change will now take place
in Pillow 7.0.
Security
========
This release catches several buffer overruns, as well as addressing
CVE-2019-16865. The CVE is regarding DOS problems, such as consuming large
amounts of memory, or taking a large amount of time to process an image.
In RawDecode.c, an error is now thrown if skip is calculated to be less than
zero. It is intended to skip padding between lines, not to go backwards.
In PsdImagePlugin, if the combined sizes of the individual parts is larger than
the declared size of the extra data field, then it looked for the next layer by
seeking backwards. This is now corrected by seeking to (the start of the layer
+ the size of the extra data field) instead of (the read parts of the layer +
the rest of the layer).
Decompression bomb checks have been added to GIF and ICO formats.
An error is now raised if a TIFF dimension is a string, rather than trying to
perform operations on it.
