NVD Description

Note: Versions mentioned in the description apply only to the upstream webkitgtk4-devel package and not the webkitgtk4-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
