{"id":"CVE-2024-21634","state":"PUBLISHED","title":"Ion Java StackOverflow vulnerability","description":"Amazon Ion is a Java implementation of the Ion data notation. Prior to version 1.10.5, a potential denial-of-service issue exists in `ion-java` for applications that use `ion-java` to deserialize Ion text encoded data, or deserialize Ion text or binary encoded data into the `IonValue` model and then invoke certain `IonValue` methods on that in-memory representation. An actor could craft Ion data that, when loaded by the affected application and/or processed using the `IonValue` model, results in a `StackOverflowError` originating from the `ion-java` library. The patch is included in `ion-java` 1.10.5. As a workaround, do not load data which originated from an untrusted source or that could have been tampered with.","publishedAt":"2024-01-03T22:46:03.585Z","updatedAt":"2025-11-03T21:53:26.420Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["amazon-ion ion-java"],"affected":[{"vendor":"amazon-ion","product":"ion-java","versions":[{"version":"< 1.10.5","status":"affected"}]}],"references":["https://github.com/amazon-ion/ion-java/security/advisories/GHSA-264p-99wq-f4j6","https://security.netapp.com/advisory/ntap-20241108-0002/"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:06:59.846Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/21xxx/CVE-2024-21634.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-21634","state":"PUBLISHED","datePublished":"2024-01-03T22:46:03.585Z","dateUpdated":"2025-11-03T21:53:26.420Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-12-29T03:00:44.955Z"},"containers":{"cna":{"title":"Ion Java StackOverflow vulnerability","descriptions":[{"lang":"en","value":"Amazon Ion is a Java implementation of the Ion data notation.
