gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka
LibGD) 2.2.5, as used in the imagecolormatch function in PHP before 5.6.40,
7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1, has a
heap-based buffer overflow. This can be exploited by an attacker who is
able to trigger imagecolormatch calls with crafted image data.
