CVE-2013-1978

Desbordamiento de búfer en la función read_xwd_cols en file-xwd.c en el plugin X Window Dump (XWD) de GIMP 2.6.9 y anteriores versiones permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un volcado de imagen X Window System (XWD) con más colores que las entradas del mapa de color.

Multiple stack-based buffer overflows in file-xwd.c in the X Window Dump plug-in in GIMP 2.8.2 allow remote attackers to cause a denial of service and possibly execute arbitrary code via a large blue color mask in an XWD file. Integer overflow in the load_image function in file-xwd.c in the X Window Dump plug-in in GIMP 2.6.9 and earlier, when used with glib before 2.24, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large color entries value in an X Window System image dump. Heap-based buffer overflow in the read_xwd_cols function in file-xwd.c in the X Window Dump plug-in in GIMP 2.6.9 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via an X Window System image dump with more colors than color map entries. The updated packages have been patched to correct these issues.
