3DescriptionCVE.org
A security vulnerability has been detected in Open Asset Import Library Assimp up to 6.0.2. The impacted element is the function MD5Importer::MakeDataUnique of the file code/AssetLib/MD5/MD5Loader.cpp. The manipulation of the argument iNewIndex leads to heap-based buffer overflow. The attack can only be performed from a local environment. The identifier of the patch is bf9dabb617c46e5133dac65cca6bff177917afcb. Applying a patch is the recommended action to fix this issue.
AnalysisAI
Heap-based buffer overflow in Open Asset Import Library (Assimp) through version 6.0.2 allows a local low-privilege attacker to corrupt heap memory by supplying a crafted MD5 mesh file. The root cause, confirmed by the patch diff, is that MakeDataUnique() pre-allocated only faces × 3 vertex slots when the output can grow to numOrigVerts + faces × 3 - meshes declaring more original vertices than face corners overflow the allocation. …

Vulnerability AssessmentAI
| Exploitation | The vulnerability is triggered when Assimp processes a crafted MD5 mesh file (`.md5mesh`) in which the number of original declared vertices exceeds the number of face-corner index slots (`mFaces.size() × 3`). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) scores 4.8, reflecting a strictly local attack path with low-privilege requirements and constrained impact across confidentiality, integrity, and availability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Build Assimp from the patched commit `bf9dabb617c46e5133dac65cca6bff177917afcb` (https://github.com/assimp/assimp/commit/bf9dabb617c46e5133dac65cca6bff177917afcb) until a formally tagged release is published incorporating PR #6718. … Detailed patch versions, workarounds, and compensating controls in full report. |
