cJSON Project

cJSON v1.7.17 was discovered to contain a segmentation violation, which can trigger through the second parameter of function cJSON_SetValuestring at cJSON.c.

parse_string in cJSON before 1.7.18 has a heap-based buffer over-read via {"1":1, with no trailing newline if cJSON_ParseWithLength is called.

cJSON 1.7.15 might allow a denial of service via a crafted JSON document such as {"a": true, "b": [ null,9999999999999999999999999999999999999999999999912345678901234567]}.
