Description Oleg Sushchenko 2026-11-03 14:46:06 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Scribus before 1.6.7 contains a heap out-of-bounds write vulnerability in the scimgdataloader_psd loader that uses unchecked PSD file values as lookup array indexes. Attackers can convince users to place or import a crafted PSD file to corrupt heap memory, causing crashes and potentially code execution as the user.
