CVE-2017-2903: An exploitable integer overflow exists in the DPX loading functionality of the Blender open-source 3d creat...

An exploitable integer overflow exists in the DPX loading functionality of the Blender open-source 3d creation suite version 2.78c. A specially crafted '.cin' 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.

Security readout for executives and security teams

Plain-English summary

CVE-2017-2903 is a file-parsing flaw in Blender 2.78c. If a user imports or uses a malicious .cin asset, Blender can overflow memory and potentially run attacker-controlled code with the user's application privileges.

Executive priority

Prioritize remediation where Blender processes outside assets. The business risk is user workstation compromise from a malicious media file, not remote unauthenticated server exploitation.

Technical view

The vulnerability is an integer overflow in Blender's DPX loading functionality. A crafted .cin file can trigger a buffer overflow, enabling code execution in the Blender process. The CVSS 3.0 score is 8.8, with user interaction required.

Likely exposure

Exposure is most likely on workstations or render workflows running Blender 2.78c that process externally supplied .cin, DPX, or related media assets through the sequencer.

Exploitation context

The source bundle does not show known active exploitation or KEV listing. Exploitation requires convincing a user to open or use a crafted asset, making phishing, shared project files, or third-party asset intake the practical risk path.

Researcher notes

TALOS-2017-0410 is the primary technical reference. The affected product named in the bundle is Blender v2.78c only. No CWE is listed. Do not assume broader version impact, active exploitation, or exact fixed versions beyond the cited advisories.

Mitigation direction

  • Identify and replace Blender 2.78c where present.
  • Apply vendor or distribution Blender security updates referenced by Debian advisories.
  • Restrict untrusted .cin and DPX asset handling until updated.
  • Treat external project assets as untrusted input in creative workflows.

Validation and detection

  • Inventory installed Blender versions across artist and render systems.
  • Confirm whether Blender 2.78c is present in managed images or packages.
  • Review asset intake workflows for untrusted .cin or DPX files.
  • Check vendor or distribution advisories for the deployed fixed package.
