Goldstein Lyor reassigned SSHD-634:
-----------------------------------
Assignee: Goldstein Lyor
> Suspicious read buffer re-use in write command
> ----------------------------------------------
>
> Key: SSHD-634
> URL: https://issues.apache.org/jira/browse/SSHD-634
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 1.0.0
> Reporter: Eugene Petrenko
> Assignee: Goldstein Lyor
>
> From time to time I saw a {{Bad packet length ###}} errors from SSH clients
> that calls commands to the SSHD server running with Apache SSHD.
> It may turn out there are some issues in the implementation.
> I found one suspicious usage of buffers around
> {{org.apache.sshd.common.channel.AbstractChannel#sendResponse}} method. As
> far as I see from the code it uses the read buffer as a place to generate a
> write packet command. Maybe it's worth to create a fresh buffer here to avoid
> it be updated from the other thread while it is put to a write queue
