gdk-pixbuf is an image loading library that can be extended by loadable modules for new image formats. It is used by toolkits such as GTK+ or clutter.

An integer overflow, leading to a heap-based buffer overflow, was 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.
