| 标题 | Assimp commit 17c12da Heap-based Buffer Overflow |
|---|
| 描述 | A heap-buffer-overflow vulnerability exists in Assimp's glTF2 importer within the `glTFCommon::CopyValue` function at `glTFCommon.h:178`. The flaw is caused by insufficient input validation when parsing node transformation matrices. When processing a malicious glTF 2.0 file with an invalid matrix that has insufficient data length, the program allocates only 1-byte heap memory but attempts to read 64 bytes (16 float values for a 4x4 matrix) without boundary checks. This out-of-bounds memory read leads to an immediate application crash and may potentially expose sensitive heap memory information. Remote attackers can exploit this vulnerability to cause a denial-of-service (DoS) condition or information disclosure via a crafted glTF file. |
