CVE-2024-21634
Ion Java StackOverflow vulnerability
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.
