An exploitable integer overflow exists in the 'CustomData' Mesh loading
functionality of the Blender open-source 3d creation suite. A .blend file with
a specially crafted external data file can cause an integer overflow resulting
in a buffer overflow which can allow for code execution under the context of
the application. An attacker can convince a user to edit an object within a
.blend library in their Scene in order to trigger this vulnerability.
