The imagegammacorrect function in ext/gd/gd.c in PHP before 5.6.25 and 7.x
before 7.0.10 does not properly validate gamma values, which allows remote
attackers to cause a denial of service (out-of-bounds write) or possibly
have unspecified other impact by providing different signs for the second
and third arguments.

| tyhicks | The flaw is in the PHP code sitting in front of libgd2 and libgd2 does not have a part in this particular operation. |
