Technical details

A NULL pointer dereference vulnerability exists in GIMP's SwatchBooker (SBZ) palette parsing code when a crafted palette file lacks a color-model attribute. The vulnerability occurs during string comparison in the palette import logic, which runs in the main application process without isolation. Exploitation requires local user interaction to import a malicious palette file and results in application crash (denial of service); no remote code execution or privilege escalation is possible.
