This release fixes several buffer overruns and DOS attacks.
If an FPX 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.
Overflow checks have been added when calculating the size of a memory block to be reallocated in the processing of TIFF, SGI, PCX and FLI images.
