## Overview

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds read vulnerability in read_file_dna() that reads a GLOB block field without validating its declared length. Attackers can supply a crafted .blend file with a truncated GLOB block that, when opened, triggers the out-of-bounds read and crashes Blender.

## Affected

- `Blender < 4.5.15`
- `Blender >= 5.0.0 < 5.2.3`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
