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 vulnerability, which was classified as critical, has been found in Open Asset Import Library Assimp 5.4.3. This issue affects the function Assimp::BaseImporter::ConvertToUTF8 of the file BaseImporter.cpp of the component File Handler. The manipulation leads to heap-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.(CVE-2025-2152) A vulnerability classified as critical has been found in Open Asset Import Library Assimp 5.4.3. This affects the function Assimp::ASEImporter::BuildUniqueRepresentation of the file code/AssetLib/ASE/ASELoader.cpp of the component ASE File Handler. The manipulation of the argument mIndices leads to out-of-bounds read. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 6.0 is able to address this issue. The patch is named 7c705fde418d68cca4e8eff56be01b2617b0d6fe. It is recommended to apply a patch to fix this issue.(CVE-2025-3015) A vulnerability, which was classified as critical, has been found in Open Asset Import Library Assimp 5.4.3. Affected by this issue is the function Assimp::LWO::AnimResolver::UpdateAnimRangeSetup of the file code/AssetLib/LWO/LWOAnimation.cpp of the component LWO File Handler. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.(CVE-2025-3158) A vulnerability, which was classified as critical, was found in Open Asset Import Library Assimp 5.4.3. Affected is the function Assimp::MD2Importer::InternReadFile in the library code/AssetLib/MD2/MD2Loader.cpp of the component Malformed File Handler. The manipulation of the argument Name leads to stack-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component.(CVE-2025-3196) An update for assimp is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of critical.
