> Key: AVRO-3049
> URL: https://issues.apache.org/jira/browse/AVRO-3049
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Reporter: John Karp
> Assignee: John Karp
> Priority: Major
>
> There are several checks on string length in BinaryDecoder. However, it lacks the same checks for byte arrays.
> * Negative lengths lead to IllegalArgumentException instead of org.apache.avro.AvroRuntimeException
> * Pathologically large (however legal) arrays can be allocated. Some applications will be suffer denial of service if they are forced to allocate 1 GB arrays repeatedly.
