The following vulnerability was published for libgxps.

| There is a stack-based buffer over-read in calling GLib in the function
| gxps_images_guess_content_type of gxps-images.c in libgxps through
| 0.3.0 because it does not reject negative return values from a
| g_input_stream_read call. A crafted input will lead to a remote denial
| of service attack.
