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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product reads data past the end, or before the beginning, of the intended buffer.
