NULL Pointer Dereference in Assimp 6.0.5 Ogre Importer

Sources read

Source agreement

0/2

Evidence confidence

%47

Short explanation

Assimp 6.0.5 and earlier versions contain a NULL pointer dereference in the Ogre3D importer due to unvalidated bone indices. An attacker can supply a .mesh or .skeleton file referencing a missing bone to crash the host application.

Why does it matter?

The crash causes denial‑of‑service and can disrupt secure environments.

What should be done?

Monitor vendor advisories
Apply patch when released
Upgrade to newer Assimp version
Disable Ogre importer if not needed
Validate input files

Show the technical text from the sources

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.
