Vulnerabilities

An issue was discovered in json-c from 20200420 (post 0.14 unreleased code) through 0.15-20200726.

json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend.

The hash functionality in json-c before 0.12 allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted JSON data, involving collisions.

Buffer overflow in the printbuf APIs in json-c before 0.12 allows remote attackers to cause a denial of service via unspecified vectors.
