GraphicsMagick encounter a read beyond an allocated heap buffer when reading CMYKA TIFF files which claim to offer fewer samples per pixel than required. A maliciously crafted file could cause the application to crash. Please see bug 611356 for details.

Probably only affected when "tiff" USE flag is set which isn't the default.
