Description OSIDB Bzimport 2026-07-06 19:00:25 UTC 
Stack-based out-of-bounds write in GIMP's Seattle FilmWorks (SFW94A) loader. In load_image() in file-seattle-filmworks.c, a stack VLA sized as file_size - 0xE0 is allocated, but subsequent bounds checks continue to use file_size. A crafted SFW file can therefore drive the JPEG marker search and repair logic past the VLA boundary and corrupt stack memory.

- Function: load_image()
- File: plug-ins/common/file-seattle-filmworks.c:261-428
