CVE-2017-2905: An exploitable integer overflow exists in the bmp loading functionality of the Blender open-source 3d creat...

An exploitable integer overflow exists in the bmp loading functionality of the Blender open-source 3d creation suite version 2.78c. A specially crafted '.bmp' 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 loads a malicious BMP asset through the sequencer. The bug can corrupt memory and may allow code execution as the Blender user. It requires user interaction, but impact could include workstation compromise, data exposure, or disruption of creative pipelines.

Executive priority

Treat this as high priority if Blender is used with external assets or legacy Debian packages. The issue is old, but unfixed creative workstations can become an entry point because exploitation depends on opening a malicious file, not server exposure.

Technical view

The flaw is an integer overflow in Blender's BMP loading functionality that can lead to a buffer overflow. The CVSS 3.0 score is 8.8 with network attack vector and required user interaction. The provided affected product is Blender v2.78c. Debian published security updates in 2018.

Likely exposure

Exposure is most likely on desktop, rendering, or asset-processing systems still running Blender 2.78c or affected Debian Blender packages. Risk increases where users import external BMP files or third-party media assets into Blender workflows.

Exploitation context

The described attack requires persuading a user to use a crafted .bmp file as an asset via Blender's sequencer. The source bundle does not show CISA KEV listing or active in-the-wild exploitation. Talos reports exploitability and potential code execution.

Researcher notes

Evidence is specific to Blender 2.78c BMP loading and user-triggered sequencer asset handling. The bundle does not provide CWE mapping, upstream Blender patch details, or proof of exploitation. Validation should focus on version inventory and media ingestion workflows.

Mitigation direction

  • Inventory Blender installations and identify version 2.78c or affected Debian packages.
  • Apply Debian Blender security updates where Debian packages are used.
  • Check Blender or distribution guidance for fixed supported versions.
  • Restrict untrusted BMP assets from entering Blender workflows.
  • Use least-privileged, isolated workstations for external media processing.

Validation and detection

  • Confirm Blender version and package source on creative and rendering systems.
  • Review asset ingestion paths for external BMP or project files.
  • Verify Debian systems include the DSA-4248 or DLA-1465-1 update level.
  • Check whether Blender processing runs under non-administrative user accounts.
