Description

Dmitry V. Levin 2011-06-25 04:35:02 MSK

"It was found that gdk-pixbuf GIF image loader gdk_pixbuf__gif_image_load()
routine did not properly handle certain return values from its 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."
