Gimp: stack vla size underflow denial of service in seattle

Description

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.
