"Pillow developers report :

This release addresses several security problems, as well as
addressing CVE-2019-19911.

CVE-2019-19911 is regarding FPX images. If an image reports that it
has a large number of bands, a large amount of resources will be used
when trying to process the image. This is fixed by limiting the number
of bands to those usable by Pillow.

Buffer overruns were found when processing an SGI, PCX or FLI image.
Checks have been added to prevent this.

Overflow checks have been added when calculating the size of a memory
block to be reallocated in the processing of a TIFF image."
