Title
Gdk-pixbuf: gdk-pixbuf: denial of service via heap-based buffer overflow when processing a specially crafted jpeg image
Summary
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.
