| 标题 | Assimp commit 17c12da Divide By Zero |
|---|
| 描述 | A division-by-zero vulnerability exists in Assimp's FBX exporter within the FBXExporter::WriteObjects() function at FBXExporter.cpp:1249. The flaw occurs when processing UV channels where the component count mNumUVComponents[uvi] is zero. The code performs a division operation using this zero value without any validation check, triggering a floating-point exception (FPE) and an immediate program crash. Remote attackers can exploit this vulnerability via a maliciously crafted input file to cause a denial-of-service (DoS) condition. |
