Summary
A flaw was found in SQLite. A remote attacker could exploit a use-after-free vulnerability in the JSON extraction function.
This occurs when the program attempts to access memory after it has been freed, specifically within the `JsonParse` object. Successful exploitation of this vulnerability can lead to a service crash and a denial of service (DoS) for affected systems.
This Moderate flaw in SQLite's JSON extraction function can lead to a denial of service. Applications that process untrusted JSON input using SQLite in Red Hat products are susceptible to a service crash due to a use-after-free vulnerability.
This could impact the availability of services relying on SQLite for JSON data handling. Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
