gdk-pixbuf vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.10
- Ubuntu 20.04 LTS


GDK-PixBuf could be made to crash if it opened a specially crafted file.

Software Description:
- gdk-pixbuf: GDK Pixbuf library


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.
