Doc Text:
A flaw was found in Scribus. When decoding planar pixel data in the Mac PICT image loader, the application does not properly validate image dimensions, leading to an out-of-bounds read vulnerability. By convincing a user to import or open a specially crafted PICT file, an attacker can trigger an application crash, resulting in a Denial of Service (DoS), or potentially expose sensitive memory contents.

Description OSIDB Bzimport 2026-10-30 15:49:36 UTC 
Scribus before 1.6.7 contains an out-of-bounds read vulnerability in the Mac PICT image loader and import plugin when decoding planar pixel data. Attackers can supply a crafted PICT file with manipulated dimensions that, when placed or imported, causes heap over-reads leading to crashes or heap memory disclosure.
