## Overview

Scribus before 1.6.7 and 1.7.x before 1.7.4 contains an out-of-bounds memory access vulnerability in the importsvm plugin that fails to verify bitmap and transparency mask dimensions match. Attackers can supply a crafted SVM file with mismatched mask dimensions to trigger heap reads and writes, causing crashes or code execution as the user.

## 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.
