A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. Affected is the function Assimp::MD2Importer::InternReadFile in the library code/AssetLib/MD2/MD2Loader.cpp of the component Malformed File Handler. The manipulation of the argument Name leads to stack-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component.
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 writes data past the end, or before the beginning, of the intended buffer.
