It was discovered that the GDK-PixBuf library contained an integer overflow

opening a crafted image file, a remote attacker could use this flaw to cause
GDK-PixBuf to crash, resulting in a denial of service, or possibly execute
arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8875)

Franco Costantini discovered that the GDK-PixBuf library contained an
out-of-bounds write error when parsing an ico file. If a user or automated
system were tricked into opening a crafted ico file, a remote attacker could
use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service.
