CVE-2026-19969: Buffer Overflow in Open Asset Import Library Assimp
A security vulnerability has been detected in Open Asset Import Library Assimp 17c12da. The impacted element is the function Assimp::MDLImporter::GenerateOutputMeshes_3DGS_MDL7 of the file code/AssetLib/MDL/MDLLoader.cpp of the component 3DGS MDL7 Model Output Mesh Generator. The manipulation leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AI Analysis
Technical Summary
This vulnerability exists in the Assimp library version identified by commit 17c12da, in the function GenerateOutputMeshes_3DGS_MDL7 of the MDLLoader.cpp file. The flaw is a buffer overflow caused by improper handling of input data, which can be triggered remotely. The vulnerability has been publicly disclosed, but no official patch or remediation has been provided by the vendor at the time of this report.
Potential Impact
Successful exploitation of this buffer overflow could lead to potential memory corruption, which might allow an attacker to cause a denial of service or possibly execute arbitrary code remotely. However, the CVSS score and vector indicate the impact is limited to low integrity and availability impact with no privileges required and no user interaction needed, suggesting moderate risk.
Mitigation Recommendations
No official fix or patch is currently available from the vendor. Since the project has not responded yet, users should monitor the vendor's advisories for updates. Until a patch is released, consider limiting exposure of systems using this library to untrusted input or network sources to reduce risk.
