A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. This affects the function Assimp::CSMImporter::InternReadFile of the file code/AssetLib/CSM/CSMLoader.cpp of the component CSM File Handler. The manipulation leads to out-of-bounds write. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
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.
