Advisory Updated Date: 2016-03-29 15:30 Pacific
An access flaw was discovered in the OpenSSH client where it did not correctly handle failures to generate authentication cookies for untrusted X11 forwarding. A malicious or compromised remote X application could possibly use this flaw to establish a trusted connection to the local X server, even if only untrusted X11 forwarding was requested.
Affected Packages:
openssh
Issue Correction:
Run yum update openssh to update your system.
