Name        : gdk-pixbuf2
Product     : Fedora 15
Version     : 2.23.3
Release     : 2.fc15
URL         : http://www.gt.org
Summary     : An image loading library
Description :
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.

--------------------------------------------------------------------------------
Update Information:

It was found that gdk-pixbuf GIF image loader gdk_pixbuf__gif_image_load()
routine did not properly handle certain return values from their subroutines. A
remote attacker could provide a specially-crafted GIF image, which once opened
in an application, linked against gdk-pixbuf would lead to gdk-pixbuf to return
partially initialized pixbuf structure, possibly having huge width and height,
leading to that particular application termination due excessive memory use.

The CVE identifier of CVE-2011-2485 has been assigned to this issue.
