| タイトル | Open Asset Import Library Assimp 5.4.3 Heap-based Buffer Overflow |
|---|
| 説明 | A heap-buffer-overflow vulnerability was discovered in the Assimp::MD3Importer::ValidateSurfaceHeaderOffsets function within the Assimp Library. This issue occurs when processing certain malformed files, leading to an out-of-bounds read and potential application crash.
The vulnerability arises in the Assimp::MD3Importer::ValidateSurfaceHeaderOffsets function defined in code/AssetLib/MD3/MD3Loader.cpp at line 397. The function seems to lack judgment on pointer validity, resulting in the use of wild pointers (according to ASAN report). |
