### Description
It was found that the gdk-pixbuf GIF image loader routine
`gdk_pixbuf__gif_image_load()` did not properly handle certain return values
from its subroutines. A remote attacker could provide a specially-crafted GIF
image, which, once opened in Pidgin, would lead gdk-pixbuf to return a partially
initialized pixbuf structure. Using this structure, possibly containing a huge
width and height, could lead to the application being terminated due to
excessive memory use.
### Mitigation
Change Pidgin to look at the GError parameter in addition to the return value
when calling certain gdk-pixbuf functions.
