Summary

assimp security update

Details

Assimp is a library to load and process geometric scenes from various data formats. Assimp aims to provide a full asset conversion pipeline for use in game engines and real-time rendering systems of any kind, but is not limited to this purpose.

Security Fix(es):

A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. Affected is the function Assimp::MD3Importer::ValidateSurfaceHeaderOffsets of the file code/AssetLib/MD3/MD3Loader.cpp of the component File Handler. The manipulation leads to heap-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used.(CVE-2025-3549)

A vulnerability was found in Open Asset Import Library Assimp 5.4.3 and classified as problematic. This issue affects the function MDCImporter::ValidateSurfaceHeader of the file assimp/code/AssetLib/MDC/MDCLoader.cpp. The manipulation of the argument pcSurface2 leads to out-of-bounds read. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The project decided to collect all Fuzzer bugs in a main-issue to address them in the future.(CVE-2025-5165)

A vulnerability was found in Open Asset Import Library Assimp 5.4.3. It has been rated as problematic. Affected by this issue is the function MDLImporter::ImportUVCoordinate_3DGS_MDL345 of the file assimp/code/AssetLib/MDL/MDLLoader.cpp. The manipulation of the argument iIndex leads to out-of-bounds read. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The project decided to collect all Fuzzer bugs in a main-issue to address them in the future.(CVE-2025-5168)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
