Open Asset Import Library Assimp 3DGS MDL7 Model Output Mesh Generator MDLLoader.cpp GenerateOutputMeshes_3DGS_MDL7 buffer overflow
Noroxi assessment
Priority: Monitor (action score 8/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.50% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 2.1.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
