Description

Kitware VTK (Visualization Toolkit) through 9.5.0 contains a heap buffer overflow vulnerability in vtkGLTFDocumentLoader. When processing specially crafted GLTF files, the copy constructor of Accessor objects fails to properly validate buffer boundaries before performing memory read operations.

CWE

KEV

CWE ID	Description
CWE-122	A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Attack-Flow Graph

Executive Summary

This vulnerability is a heap buffer overflow in the vtkGLTFDocumentLoader component of Kitware VTK up to version 9.5.0. It occurs because the copy constructor of Accessor objects does not properly validate buffer boundaries when processing specially crafted GLTF files, leading to out-of-bounds memory reads. [1]

Impact Analysis

The vulnerability can lead to a heap buffer overflow, which may cause application crashes or potentially allow an attacker to execute arbitrary code or cause denial of service by exploiting the improper memory handling during GLTF file processing. [1]
