Descriptions
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.
Vulnerabilidad de consumo de pila en la función gdImageFillToBorder en gd.c en la GD Graphics Library (también conocida como libgd) en versiones anteriores a 2.2.2, como se utiliza en PHP en versiones anteriores a 5.6.28 y 7.x en versiones anteriores a 7.0.13, permite a atacantes remotos provocar una denegación de servicio (violación de segmentación) a través de una llamada imagefilltoborder manipulada que desencadena el uso de un valor de color negativo.
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.
