py-pillow -- Integer overflow in Resample.c

The Pillow maintainers report: If a large value was passed into the new size for an image, it is possible to overflow an int32 value passed into malloc, leading the malloc’d buffer to be undersized. These allocations are followed by a loop that writes out of bounds. This can lead to corruption on...
