Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Ion Java (com.amazon.ion:ion-java) versions before 1.10.5 are vulnerable to a denial-of-service issue. An attacker who can supply crafted Ion text or binary data that an application deserializes, or processes through the IonValue model, can trigger a StackOverflowError. Upgrade com.amazon.ion:ion-java to 1.10.5 or later; until then, only load Ion data from trusted sources. The software.amazon.ion:ion-java package has no fixed version listed.
