| Impact: | Moderate | What is this? |
The x11_open_helper function in channels.c in ssh in OpenSSH before6.9, 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.
