When openssh 5.3p1 is complied without using the "--with-libedit", the result is working fine. So, the issue is caused by making the package with "--with-libedit" and the libedit has some issue in handling the tty attributes. Created attachment 801581 [details]
[PATCH] libedit: restore original term attributes on exit
Restoring of the original terminal attributes on exit was implemented upstream later on. The attached patch implements it for RHEL-6. Otherwise the described behavior does not differ from upstream, neither has been confirmed as a bug yet.
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate, in the next release of Red Hat Enterprise Linux. *** Bug 1008042 has been marked as a duplicate of this bug. *** Just restore tty setting at exit is not good enough: the sftp needs to allow user to control tty echo setting, so if a user has turned off echo for the tty, the sftp should not turn it back on, because that's what the user wants, and if the user wants to see the input, he/she could do it by turning echo on before exec sftp, but if the sftp will always turn on echo, then the user will have no way to control the behavior, that's not right and not good for security if the user wants to hide the activities. Red Hat Enterprise Linux 6 is in the Production 3 Phase. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. The official life cycle policy can be reviewed here: http://redhat.com/rhel/lifecycle This issue does not meet the inclusion criteria for the Production 3 Phase and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification. Note that a strong business justification will be required for re-evaluation.
