## Overview

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability caused by integer overflow in ptcache_data_alloc() when reading point cache files. Attackers can supply a crafted point cache file with a large totpoint value alongside a .blend file to crash Blender or execute code as the user.

## 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.
