Thanks for the fast reply.
> AbstractChannel.handleWindowAdjust(...) / Window.expand() don't check for
> integer overflow

> Key: SSHD-794
> URL: https://issues.apache.org/jira/browse/SSHD-794
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.14.0
> Environment: Any.
> Reporter: Curd Reinert
> Fix For: 1.4.0
>
>
> In AbstractChannel.handleWindowAdjust(Buffer), the window size is read from
> the buffer and passed to the window. In Window.expand(int), the window is
> added to the current size. If the current size is > 0 and the maximum allowed
> window adjustment (2^31 -1) is passed, size will become negative. This causes
> a loop when trying to read from / write to this channel which cosumes one
> processor core.
> The resulting size should be checked to be > 0.
> I see that this has been done for the 1.x release. Any chance that this can
> be fixed in 0.15?
