gdk-pixbuf vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

Summary:
GDK-PixBuf could be made to crash if it opened a specially crafted file.
Software Description: - gdk-pixbuf: GDK Pixbuf library
Details:
It was discovered that the GDK-PixBuf library did not properly handle certain GIF images. If an user or automated system were tricked into opening a specially crafted GIF file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service.
