      <title>GHSA-264p-99wq-f4j6 — Ion Java StackOverflow vulnerability</title>
      <link>https://db.gcve.eu/vuln/ghsa-264p-99wq-f4j6</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Maven: com.amazon.ion:ion-java, Maven: software.amazon.ion:ion-java&lt;/p&gt;
&lt;p&gt;### Impact&lt;/p&gt;
&lt;p&gt;A potential denial-of-service issue exists in `ion-java` for applications that use `ion-java` to:&lt;/p&gt;
&lt;p&gt;* 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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;Impacted versions: &amp;lt;1.10.5&lt;/p&gt;
&lt;p&gt;### Patches&lt;/p&gt;
&lt;p&gt;The patch is included in `ion-java` &amp;gt;= 1.10.5.&lt;/p&gt;
&lt;p&gt;### Workarounds&lt;/p&gt;
&lt;p&gt;Do not load data which originated from an untrusted source or that could have been tampered with. **Only load data you trust.**&lt;/p&gt;
&lt;p&gt;----&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
