CVE-2013-6371
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.
Does this matter?
Lower severity and a low EPSS score (3.11%). Track it; it rarely justifies an emergency change on its own.
