Json-cCVEs & Vulnerabilities
4 CVEs affecting Json-c products, tracked from the National Vulnerability Database, with CVSS/EPSS scores and exploitation status.
Most Affected Products
An issue was discovered in json-c from 20200420 (post 0.14 unreleased code) through 0.15-20200726. A stack-buffer-overflow exists in the auxiliary sample program json_parse which is located in the function parseit.
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.
