Summary
A vulnerability has been detected in the Assimp library (Open Asset Import Library) version 17c12da. The issue affects the function Assimp::MDLImporter::ParseBoneTrafoKeys_3DGS_MDL7 in file code/AssetLib/MDL/MDLLoader.cpp, where manipulation of arguments transmatrix_count/pcBoneTransforms leads to buffer overflow. The attack can be initiated remotely, and the exploit is publicly available.
Risk Assessment
Buffer overflow could allow remote code execution or cause a crash in applications using the Assimp library, posing a serious risk to systems processing 3D files.
Recommendation
It is recommended to apply the patch immediately (identifier: 50d767984e78d51b53e2020fdf0967fd624bc377) and update the library to a patched version.
