CVE-2017-12081

An exploitable integer overflow exists in the upgrade of a legacy Mesh
attribute of the Blender open-source 3d creation suite v2.78c. A specially
crafted .blend 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 open the file or use it as
a library in order to trigger this vulnerability.
