GHSA-264p-99wq-f4j6 Ion Java StackOverflow vulnerability

• Maven com.amazon.ion:ion-java: < 1.10.5 → fixed in 1.10.5 • Maven software.amazon.ion:ion-java: < 1.10.5 (no fix yet)

Impact 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. Impacted versions: = 1.10.5. Workarounds Do not load data which originated from an untrusted source or that could have been tampered with. Only load data you trust. ---- If you have any questions or comments about this advisory, we ask that you contact AWS/Amazon Security via our vulnerability reporting page [1] or directly via email to [email protected].
