A vulnerability classified as problematic has been found in Open Asset Import Library Assimp 5.4.3. This affects the function MDLImporter::ParseSkinLump_3DGS_MDL7 of the file assimp/code/AssetLib/MDL/MDLMaterialLoader.cpp. The manipulation 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.
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.
