A vulnerability, which was classified as critical, has been found in Open Asset Import Library Assimp 5.4.3. This issue affects the function Assimp::BaseImporter::ConvertToUTF8 of the file BaseImporter.cpp of the component File Handler. The manipulation leads to heap-based buffer overflow. The attack may be initiated 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.
The product writes data past the end, or before the beginning, of the intended buffer.
