Integer overflow in the load_image function in file-xwd.c in the X Window Dump (XWD) 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 (crash) and possibly execute arbitrary code via a large color entries value in an X Window System (XWD) image dump.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
