## Overview

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an integer overflow vulnerability in the scimgdataloader_tiff TIFF loader that allows attackers to trigger a heap overflow via crafted tile dimensions. Attackers can supply a tiled TIFF with large tile width, height and sample values for a user to import, corrupting heap memory to crash Scribus or execute code.

## Affected

- `Scribus < 1.6.7`
- `Scribus >= 1.7.0 < 1.7.4`

## Remediation

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