An update for assimp is now available for openEuler-24.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-4143 Final 1.0 1.0 2026-09-30 Initial 2026-09-30 2026-09-30 openEuler SA Tool V1.0 2026-09-30 assimp security update An update for assimp is now available for openEuler-24.03-LTS-SP4 Assimp is a library to load and process geometric scenes from various data formats. Assimp aims to provide a full asset conversion pipeline for use in game engines and real-time rendering systems of any kind, but is not limited to this purpose. Security Fix(es): A security vulnerability has been detected in Open Asset Import Library Assimp Assimp 17c12da. The affected element is the function Assimp::MDLImporter::ParseBoneTrafoKeys_3DGS_MDL7 of the file code/AssetLib/MDL/MDLLoader.cpp of the component 3DGS MDL7 Bone Transformation Key Parser. The manipulation of the argument transmatrix_count/pcBoneTransforms leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The identifier of the patch is 50d767984e78d51b53e2020fdf0967fd624bc377. It is recommended to apply a patch to fix this issue.(CVE-2026-19999) An update for assimp is now available for master/openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP3/openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
