CVE-2026-79902
Gimp: stack vla size underflow denial of service in seattle
A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array (VLA) on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting in a denial of service.
Fixes and workarounds
Workaround
To mitigate this vulnerability, do not open SFW files from untrusted sources with GIMP.
