An exploitable integer overflow exists in the way that the Blender open-source 3d creation suite v2.78c converts text rendered as a font into a curve. 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.

Security readout for executives and security teams

Plain-English summary

Blender 2.78c can be compromised when a user opens a malicious .blend file or uses it as a library. The flaw is in font-to-curve conversion and can let attacker-supplied file content run code with the user’s Blender privileges.

Executive priority

Treat this as a high-priority legacy software risk if Blender 2.78c exists in creative or rendering environments. The business risk is workstation or pipeline compromise from a malicious project file, not remote unauthenticated server takeover.

Technical view

CVE-2017-12103 is an integer overflow in Blender 2.78c when converting rendered text fonts into curves. The overflow can lead to a buffer overflow and code execution. CVSS 3.0 is 8.8, with no privileges required but user interaction required.

Likely exposure

Exposure is most likely on workstations, render systems, or automated content pipelines that still run Blender 2.78c and process third-party .blend assets. Current supported Blender installations are not shown as affected in the supplied sources.

Exploitation context

The supplied sources describe a malicious file attack path. A victim must open the crafted .blend file or use it as a library. The CVE is not listed as KEV, and the bundle provides no cited evidence of active exploitation.

Researcher notes

Key constraints are user interaction and affected version specificity. The provided evidence supports code execution from crafted .blend content in Blender 2.78c, but does not provide KEV status, active exploitation evidence, or complete fixed-version details beyond referenced security updates.

Mitigation direction

  • Upgrade Blender through vendor or distribution security update channels.
  • Apply relevant Debian blender security updates where Debian packages are used.
  • Avoid opening untrusted .blend files on vulnerable Blender versions.
  • Restrict third-party asset ingestion in automated render or content pipelines.
  • Check Blender and OS vendor guidance for fixed version details.

Validation and detection

  • Inventory systems for Blender 2.78c installations.
  • Identify render workers that process external .blend files.
  • Confirm Debian DSA or DLA blender updates are applied where applicable.
  • Review asset intake workflows for untrusted .blend file handling.
  • Verify vulnerable Blender versions are removed or isolated.
