Description Stefan Cornelius 2017-12-11 11:44:13 UTC
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.

Actually, it seesm like RHEL7 is not affected. We have a patch (libgxps-0.2.4-GXPSImage.patch), which appears to always cause a crash shortly before reaching the vulnerable code path.
