CVE-2026-104067 · Severity: high · CVSS 7.8 · Published 2026-10-30

Scribus is a desktop publishing application used by designers to create professional layouts and documents. A crafted SVM (StarView Metafile) document with mismatched bitmap and mask dimensions can cause the application to read or write outside allocated memory, potentially leading to a crash or allowing an attacker to execute arbitrary code when a user opens the malicious file.

## How to fix

- Fixed in 1.6.7

## Technical details

The importsvm plugin fails to validate that bitmap and transparency mask dimensions match before processing image data, resulting in an out-of-bounds heap access. The vulnerability requires user interaction (opening a crafted SVM file) but no authentication. The fix adds dimension validation, overflow checks, and stream boundary verification in the image processing code.
