Descriptions

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.

Amazon Ion es una implementación Java de la notación de datos de Ion. Antes de la versión 1.10.5, existe un posible problema de denegación de servicio en `ion-java` para aplicaciones que usan `ion-java` para deserializar datos codificados de texto Ion, o deserializar texto Ion o datos codificados binarios en `IonValue `modelo y luego invocar ciertos métodos `IonValue` en esa representación en memoria. Un actor podría crear datos de Ion que, cuando los carga la aplicación afectada y/o los procesa usando el modelo "IonValue", dan como resultado un "StackOverflowError" que se origina en la librería "ion-java". El parche está incluido en `ion-java` 1.10.5. Como workaround, no cargue datos que se hayan originado en una fuente que no sea de confianza o que puedan haber sido manipulados.

A vulnerability was found in Amazon Ion, an implementation of Ion data notation. Ion-java may be affected by denial of service (DoS) due to issues while deserializing encoded data into IonValue. A maliciously crafted Ion data structure may be processed and cause a StackOverflowError, leaving the application in an unreliable state.
