Technical details

The vulnerability is a NULL pointer dereference in OgreStructs.cpp where the Ogre3D importer fails to validate bone indices before use. When processing a crafted .mesh or .skeleton file that references a non-existent bone, the BoneById() function returns null but is dereferenced without checking, causing a crash. This requires the attacker to control the input file supplied to the application.
