Description
Open Asset Import Library (assimp) through 6.0.5 contains a NULL pointer dereference vulnerability in the Ogre3D binary mesh importer's OgreBinarySerializer::ReadAnimationKeyFrames() handling of unvalidated animation track targets. Attackers can supply a crafted .mesh file with a morph animation track targeting a missing submesh or absent shared geometry to crash the host process.
A NULL pointer dereference vulnerability has been identified in the Open Asset Import Library (assimp) version 6.0.5 and prior, within the Ogre3D binary mesh importer.
