------------------------------------
Fix Version/s: 2.13
> Vulnerability in thin client protocol leads to OOM
> --------------------------------------------------
>
> Key: IGNITE-15921
> URL: https://issues.apache.org/jira/browse/IGNITE-15921
> Project: Ignite
> Issue Type: Improvement
> Components: thin client
> Affects Versions: 2.11
> Reporter: Ilya Kazakov
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Fix For: 2.13
>
>
> As thin client protocol interprets first 4 bytes as message size and allocate
> array for it. Any "big" 4 bytes sent on thin client port could leads to OOM.
> Some ideas to resolve:
> - print WARN in case of big client message
> - allocate array not for all message, but allocate it gradually.
> - read more then first4 bytes to understand is it real client message, or it
> is some trash.
