How to Fix CVE-2024-21634

To remediate this vulnerability, upgrade all affected Ion java dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.amazon.ion:ion-java fixed: 1.10.5 
<dependency>
    <groupId>com.amazon.ion</groupId>
    <artifactId>ion-java</artifactId>
    <version>1.10.5</version>
</dependency>
software.amazon.ion:ion-java fixed: Latest secure release 
<dependency>
    <groupId>software.amazon.ion</groupId>
    <artifactId>ion-java</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.amazon.ion

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-21634, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.amazon.ion

Analyze the terminal output to locate any version of Ion java in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.amazon.ion command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Ion java, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.** ---- 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 [aws-security@amazon.com](mailto:aws-security@amazon.com). Please do not create a public GitHub issue. [1] https://aws.amazon.com/security/vulnerability-reporting
