Descriptions

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.

La función imagetruecolortopalette en ext/gd/gd.c en PHP en versiones anteriores a 5.6.25 y 7.x en versiones anteriores a 7.0.10 no valida adecuadamente los valores de gama, lo que permite a atacantes remotos provocar una denegación de servicio (escritura fuera de límites) o tener otro posible impacto no especificado proporcionando diferentes signos para el segundo y tercer argumento.
