What is CVE-2026-79902?

A flaw has been identified in the Seattle FilmWorks plugin for GIMP, which processes specially crafted SFW image files. The vulnerability arises from the plugin allocating a Variable-Length Array (VLA) on the stack without conducting proper integer overflow checks. This oversight allows for unbounded stack allocation, potentially causing the application to crash and resulting in a denial of service. Users of the affected plugin should take precautionary measures to ensure system stability.

Affected Version(s)

GIMP 3.1.4
