How to fix?

Upgrade Oracle:6 openssh-clients to version 0:5.3p1-117.el6 or higher.
This issue was patched in ELSA-2016-0741.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-clients package and not the openssh-clients package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window.
