CVE-2024-21634

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

Patches

The patch is included in ion-java >= 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.
