CVE-2024-21634

Date: January 3, 2024

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.
