Detailsinfo

A vulnerability, which was classified as critical, was found in Blender 3d Creation Suite 2.78c (Image Processing Software). Affected is the function multires_load_old_dm of the component blend File Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 01/11/2018. The weakness was disclosed 04/24/2018 (Website). The advisory is shared for download at debian.org. This vulnerability is traded as CVE-2017-12100 since 07/31/2017. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 103 days. During that time the estimated underground price was around $0-$5k.
