CVE-2025-70070 Details
Description
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXMeshGeometry.cpp, MeshGeometry::MeshGeometry()
A NULL pointer dereference vulnerability has been identified in Assimp version 6.0.2 within the FBX importer, specifically in the 'MeshGeometry::MeshGeometry' function. This issue allows remote attackers to cause a denial-of-service by crafting an FBX file that includes a 'Layer' element with an empty token list. When this file is imported, the parser dereferences the first token without checking if the list is non-empty, leading to a crash.
Users are advised to update to a version of Assimp that includes the fix for this vulnerability. The specific version number is currently unknown.
