## Description

A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow
vulnerability occurs in the JPEG image loader due to improper validation of
color component counts when processing a specially crafted JPEG image. A
remote attacker can exploit this flaw without user interaction, for
example, via thumbnail generation. Successful exploitation leads to
application crashes and denial of service (DoS) conditions.
