Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library (aka libgd) before 2.2.2, as used in PHP before 5.6.28 and 7.x before 7.0.13, allows remote attackers to cause a denial of service (segmentation violation) via a crafted imagefilltoborder call that triggers use of a negative color value.
An infinite recursion flaw was found in the gdImageFillToBorder() function from the gd library; also used by PHP imagefilltoborder() function, when passing a negative integer as the color parameter, triggering a stack overflow. A remote attacker with ability to force a negative color identifier when calling the function could crash the PHP application, causing a Denial of Service.
