An exploitable integer overflow exists in the PNG loading functionality of the Blender open-source 3d creation suite version 2.78c. A specially crafted .png 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 use the file as an asset via the sequencer in order to trigger this vulnerability.
