Description OSIDB Bzimport 2026-10-19 14:06:25 UTC
A flaw was found in GIMP’s SwatchBooker (SBZ) palette importer. The parser can leave the color model NULL, then still process <values> text and call strcmp(NULL, "srgb") in swatchbooker_load_text(), crashing the main GIMP process (palette import is not plug-in-isolated).
