-------------------------------------------
> Server receiving 0-length SSH_MSG_IGNORE causes Buffer Underflow exception
> --------------------------------------------------------------------------
>
> Key: SSHD-699
> URL: https://issues.apache.org/jira/browse/SSHD-699
> Project: MINA SSHD
> Issue Type: Improvement
> Affects Versions: 1.2.0
> Reporter: Johan Östling
> Assignee: Goldstein Lyor
> Priority: Minor
> Fix For: 1.3.0
>
>
> Trying to establish the length of a message with only a header byte will
> cause a buffer underflow exception. I noticed it on SSH_MSG_IGNORE, but it is
> probably general to all messages.
> Reproducible with unit test:
> {code:title=AbstractSessionTest.java|borderStyle=solid}
> @Test
> public void testZeroLengthIgnoreMessage() throws Exception {
> Buffer msg = session.createBuffer(SshConstants.SSH_MSG_IGNORE,
> Byte.SIZE);
> session.handleIgnore(msg);
> }
> {code}
> This is a regression since 0.14.0, which did not have this problem.
