Original description
The description as published by the source.
Assimp through 6.0.5 contains a NULL pointer dereference vulnerability in the Ogre3D importer that allows attackers to crash applications via unvalidated bone indices in OgreStructs.cpp. Attackers can supply a crafted .mesh and .skeleton file referencing a missing bone, causing BoneById() to return null and crash the host process.
