Heap disclosure and crash via unchecked Accessor range
Published Oct 31, 2025 · Updated Oct 31, 2025
Heap buffer overflow in Kitware VTK through 9.5.0 allows attackers to read heap memory or crash an application via a crafted GLTF file. The vtkGLTFDocumentLoader Accessor copy constructor reads buffer data without first validating that the requested accessor range stays within the backing buffer. Exploitation requires a user or application workflow to open the malicious file; the published assessment limits the impact to disclosure and service interruption.
