The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the gdImageFillToBorder function in gd.c due to stack consumption. A remote attacker can submit a specially crafted imagefilltoborder call that triggers use of a negative color value and cause the service to crash.

Update libgd to 2.2.2 or PHP to 5.6.28 or 7.0.13.
