It was found that in storage.c, the image size is not checked for negative values. This can lead to a null pointer dereference in 3.3.x, or a dereference
of junk memory prior to that.
Integer overflow vulnerabilities were found in PyImaging_MapBuffer function, specifically there's unchecked multiplication of xsize * ysize *
bytes_per_pixel where the sizes are each an int as well as unchecked addition of the size calculated above with a attacker provided offset value.
@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

@maintainer(s), do you want to stabilize?
The two vulnerabilities were already reported in bug 599608 and bug 599610 so closing as duplicate.
