Detailsinfo

A vulnerability was found in Blender 3d Creation Suite 2.78c (Image Processing Software). It has been classified as critical. Affected is some unknown processing of the component RADIANCE Loader. 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 RADIANCE loading functionality of the Blender open-source 3d creation suite version 2.78c. A specially crafted '.hdr' 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.

The bug was discovered 01/11/2018. The weakness was published 04/24/2018 (Website). The advisory is shared for download at debian.org. This vulnerability is traded as CVE-2017-2904 since 12/01/2016. 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 neither technical details nor an exploit publicly 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. The vulnerability scanner Nessus provides a plugin with the ID 111140 (Debian DSA-4248-1 : blender - security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 176431 (Debian Security Update for blender (DSA 4248-1)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 months after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (111140). Similar entries are available at VDB-117007, VDB-117008, VDB-117009 and VDB-117011. Once again VulDB remains the best source for vulnerability data.
