CVE-2017-2902: 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

Blender 2.78c can be compromised when a user imports a malicious .cin asset. The flaw is in DPX loading and can lead to code execution with the user’s application privileges. This is mainly a workstation and creative-pipeline risk, not evidence of internet-facing remote compromise.

Executive priority

Treat as high priority for creative teams using Blender with external assets. The business risk is workstation compromise through a malicious media file, but exploitation requires user interaction and no active exploitation evidence is provided.

Technical view

CVE-2017-2902 is an integer overflow in Blender’s DPX loading functionality. A crafted .cin file can trigger a buffer overflow when used through the sequencer, potentially allowing code execution in the Blender process. CVSS 3.0 is 8.8, with user interaction required.

Likely exposure

Exposure is most likely where Blender 2.78c or vulnerable Debian Blender packages process externally supplied .cin or DPX/CIN assets, especially production, rendering, training, or review workstations.

Exploitation context

The provided sources describe file-based exploitation requiring a user to open or use a crafted .cin asset via Blender’s sequencer. The bundle does not cite CISA KEV listing or other evidence of active exploitation.

Researcher notes

Talos attributes the issue to DPX loading and describes integer overflow leading to buffer overflow. The CVE record names Blender 2.78c. Sources do not provide CWE details in the bundle or a broad affected-version range beyond cited advisories.

Mitigation direction

  • Update Blender through vendor or Debian security packages referenced by DSA-4248 and DLA-1465-1.
  • Avoid opening or importing untrusted .cin assets in Blender until affected systems are updated.
  • Restrict asset intake from external parties for vulnerable Blender workstations.
  • Check Blender and distribution advisories for exact fixed package versions.

Validation and detection

  • Inventory systems running Blender, especially version 2.78c or older distribution packages.
  • Identify users or workflows that import .cin, DPX, or externally supplied media assets.
  • Confirm Debian systems include the security updates from DSA-4248 or DLA-1465-1 where applicable.
  • Document remaining exceptions and apply compensating asset-handling restrictions.
