| 标题 | Assimp commit 17c12da NULL Pointer Dereference |
|---|
| 描述 | A NULL pointer dereference vulnerability in Assimp's glTF2 importer allows attackers to cause a denial of service (DoS) via a specially crafted glTF 2.0 file. The issue exists in glTF2Asset.h:1088 within glTF2::LazyDict<glTF2::Node>::operator[]. It occurs because the LazyDict container stores a NULL pointer when the input file has animations but no nodes array, and the code dereferences this pointer without validation during animation import. |
