OESA-2026-3106 (CVE-2025-70067)
Vulnerability from osv_openeuler – Published: 2026-07-24 11:11 – Updated: 2026-08-06 11:11 – Source websiteAssimp 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):
Buffer Overflow vulnerability exists in Assimp versions up to 6.0.2 in the FBX Importer. The vulnerability occurs in aiMaterial::AddBinaryProperty, where a property key string from a crafted FBX file is copied into a fixed-size heap buffer using strcpy() without runtime length validation(CVE-2025-70067)
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXConverter.cpp and ConvertMeshMultiMaterial() method(CVE-2025-70069)
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXMeshGeometry.cpp, MeshGeometry::MeshGeometry()(CVE-2025-70070)
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXParser.cpp, ParseVectorDataArray()(CVE-2025-70071)
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXConverter.cpp, FBXConverter::ConvertMeshMultiMaterial() components(CVE-2025-70072)
A vulnerability was found in Assimp up to 6.0.4 and classified as critical.Using CWE to declare the problem leads to CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.Impacted is confidentiality, integrity, and availability.The exploit is available at github.com. It is declared as proof-of-concept. The project tagged the reported issue as bug.There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.(CVE-2026-10232)
A flaw has been found in Open Asset Import Library Assimp up to 6.0.5. Impacted is the function Assimp::CSMImporter::InternReadFile of the file code/AssetLib/CSM/CSMLoader.cpp of the component CSM File Handler. This manipulation causes heap-based buffer overflow. The attack is restricted to local execution. The exploit has been published and may be used. Patch name: eb84eec580d3f4ba2f0fd87409b7d0744620f11e. Applying a patch is the recommended action to fix this issue.(CVE-2026-14610)
