The imagetruecolortopalette function in ext/gd/gd.c in PHP before 5.6.25
and 7.x before 7.0.10 does not properly validate the number of colors,
which allows remote attackers to cause a denial of service (select_colors
allocation error and out-of-bounds write) or possibly have unspecified
other impact via a large value in the third argument.
