Yeah. I wasn't 100% sure about putting unittests in as then it would make
the attack obvious ¯\_(ツ)_/¯

> Key: PROTON-1249
> URL: https://issues.apache.org/jira/browse/PROTON-1249
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: 0.12.2
> Reporter: Dominic Evans
> Assignee: Dominic Evans
> Labels: proton-j, security
>
> In #readValue() for ArrayType, BinaryType, ListType and MapType
> decoding, if the 'count' specified is very large then it is likely to
> trigger an OutOfMemoryException. As these can come from an external data
> source, during the SASL init for example, there is a potential for a
> denial of service. The fix is to throw an IllegalArgumentException if
> the count value is larger than the amount of data available in the
> received bytes.
