Integer overflow in the _gd2GetHeader function in gd_gd2.c in the GD
Graphics Library (aka libgd) before 2.2.3, as used in PHP before 5.5.37,
5.6.x before 5.6.23, and 7.x before 7.0.8, allows remote attackers to cause

possibly have unspecified other impact via crafted chunk dimensions in an
image.
