gdk-pixbuf is an image loading library that can be extended by

found in the way gdk-pixbuf, an image loading library for GNOME,
scaled certain bitmap format images. An attacker could use a specially
crafted BMP image file that, when processed by an application compiled
against the gdk-pixbuf library, would cause that application to crash
or execute arbitrary code with the permissions of the user running the
application. (CVE-2015-4491)
