In standard Red Hat enterprise environments, curl and libcurl do not preserve HTTP state across executions by default, limiting potential exposure to custom workflows or scripts explicitly configured to maintain persistent cookie stores. Furthermore, successful exploitation requires contacting an untrusted remote endpoint that serves an oversized cookie parameter, causing the application to reset the storage file upon its subsequent run. The resulting impact is confined to session disruption without compromising host integrity or system security.", "threat_severity": "Low"}
