A vulnerability was found in Open Asset Import Library Assimp 5.4.3. It has been classified as problematic. Affected is the function MDCImporter::InternReadFile of the file assimp/code/AssetLib/MDC/MDCLoader.cpp of the component MDC File Parser. The manipulation of the argument pcVerts leads to out-of-bounds read. It is possible to launch the attack on the local host. 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.
