| عنوان | Assimp commit 17c12da Heap-based Buffer Overflow |
|---|
| الوصف | A heap-buffer-overflow vulnerability exists in Assimp's Half-Life 1 MDL loader within the `Assimp::MDL::HalfLife::HL1MDLLoader::read_animations()` function at `HL1MDLLoader.cpp:989`. The flaw is caused by insufficient array boundary validation when parsing malformed MDL files. The parser allocates an animation array of size 1, but attempts to write a second element out of bounds without verifying the remaining capacity. This out-of-bounds heap write leads to an immediate application crash and potential memory corruption. Remote attackers can exploit this vulnerability via a crafted MDL file to cause a denial-of-service (DoS) condition. |
