[jira] [Created] (AVRO-3049) Java: BinaryDecoder lacks checks on array length

John Karp created AVRO-3049:
-------------------------------

             Summary: Java: BinaryDecoder lacks checks on array length
                 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


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.
