CVE-2026-104064
Scribus before 1.6.7 and 1.7.x before 1.7.4 Heap Overflow via TIFF Tile Buffer Handling
Description
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.
