GCVE-VVD-MAGEIA-2019-3

A flaw was found in libgxps through 0.3.0. There is a heap-based buffer over-read in the function ft_font_face_hash of gxps-fonts.c. A crafted input will lead to a remote denial of service attack (CVE-2018-10733). An integer overflow flaw exists within the "gxps_images_create_from_png()" function in libgxps/gxps-images.c. An attacker can exploit this flaw to cause a heap-based buffer overflow by tricking a user into opening a specially crafted XPS document in an application using libgxps (rhbz#1524378).
