How to fix?

Upgrade Centos:6 pam_ssh_agent_auth to version 0:0.9.3-117.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pam_ssh_agent_auth package and not the pam_ssh_agent_auth package as distributed by Centos. See How to fix? for Centos: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.
