A remote attacker who can supply a crafted JSONPath expression to an application that evaluates it with json-glib's json_path_query() (or equivalent compile-and-match APIs) can trigger a non-terminating loop in the slice evaluator (for example $[:5:-1]), causing a denial of service.

No fixed upstream release is available yet; all currently shipped Red Hat and Fedora json-glib builds that include the JSONPath slice evaluator contain the vulnerable loop.", "threat_severity": "Important"}
