Description

Kitware VTK (Visualization Toolkit) through 9.5.0 contains a heap use-after-free vulnerability in vtkGLTFDocumentLoader. The vulnerability manifests during mesh object copy operations where vector members are accessed after the underlying memory has been freed, specifically when handling GLTF files with corrupted or invalid mesh reference structures.

Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a heap use-after-free issue in Kitware VTK (Visualization Toolkit) up to version 9.5.0, specifically in the vtkGLTFDocumentLoader component. It occurs during mesh object copy operations when vector members are accessed after their underlying memory has already been freed. This happens particularly when processing GLTF files that contain corrupted or invalid mesh reference structures. [1]

Impact Analysis

The vulnerability can lead to severe impacts including unauthorized remote code execution, data corruption, or application crashes because it allows attackers to exploit the use-after-free condition remotely without any privileges or user interaction. The CVSS score of 9.8 indicates a critical severity with high impact on confidentiality, integrity, and availability.
