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.

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):

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. This affects the function glTFCommon::CopyValue in the library glTFCommon.h of the component 4x4 Matrix Parser. Performing a manipulation results in heap-based buffer overflow. The attack must be initiated from a local position. The exploit…
