CVE-2017-12105: Buffer Overflow
First published: Tue Apr 24 2018(Updated: )
An exploitable integer overflow exists in the way that the Blender open-source 3d creation suite v2.78c applies a particular object modifier to a Mesh. 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 the file as a library in order to trigger this vulnerability.
