I updated python-pillow to 3.1.1 with 16095d2729, fixing these issues.

When I did that, CVE-2016-2533 wasn't named yet, but my understanding is
that the update does address it:
https://github.com/python-pillow/Pillow/commits/e5324bd3b4195d68d4a066b16d912fca30d3c4be

Python2-pil *is* vulnerable. However, it seems to have no users in our
source tree. Should we remove it?
