The JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. An application that evaluates attacker-controlled JSONPath expressions can be forced into a hang, leading to a denial of service.\n\n## Affected\n\n- `json-glib (all versions)`\n- `json-glib (all versions)`\n- `json-glib (all versions)`\n- `json-glib (all versions)`\n- `openshift/ose-rhel-coreos-8 (all versions)`\n- `openshift/ose-rhel-coreos-9 (all versions)`\n- `openshift/ose-rhel-coreos-9 (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nDo not evaluate untrusted JSONPath expressions with json_path_query() or json_path_compile()/json_path_match() until a fix is available. Prefer fixed, application-defined path expressions. In particular, reject or avoid slice expressions that specify a negative step.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
