Description
A vulnerability was detected in Assimp up to 6.0.4. Affected is the function glTF2Importer::ImportEmbeddedTextures in the library code/AssetLib/glTF2/glTF2Importer.cpp of the component TF File Handler. The manipulation results in null pointer dereference. The attack is only possible with local access. The exploit is now public and may be used. It is advisable to implement a patch to correct this issue. The pull request to fix this issue awaits acceptance.

AI Analysis

Impact

A null pointer dereference occurs in Assimp's glTF2Importer::ImportEmbeddedTextures function when processing embedded textures within a glTF file. The defect can cause the importer to crash and potentially corrupt memory, leading to a denial of service for applications relying on this library. The vulnerability does not provide direct remote impact or data exposure.

Affected Systems

Versions of the Assimp library up to and including 6.0.4 are affected. The flaw resides in the glTF asset handler, specifically in the glTF2Importer.cpp file within the TF File Handler component.

Risk and Exploitability

The CVSS score is 4.8, indicating moderate severity, and no EPSS data is available. The vulnerability is not listed in CISA's KEV catalog. Exploitation requires local access to the target system; an attacker must supply a crafted glTF file to the vulnerable importer. Because it is a local attack vector, the risk is confined to systems that use the library to process untrusted input.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Assimp to a version that includes the approved patch (e.g., 6.0.5 or later) or apply the code from the pending pull request.
  • Run the glTF importer only on trusted files and in a confined process to minimize the impact of a crash.
  • Monitor application logs for unexpected crashes or memory corruption related to glTF file processing.
