Description Laura Pardo 2018-08-01 14:11:28 UTC
An exploitable integer overflow exists in the 'multires_load_old_dm' functionality 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 a .blend file in order to trigger this vulnerability.
