OpenSSH X11 Cookie Local Authentication Bypass Vulnerability

OpenSSH is prone to a local authentication-bypass vulnerability because the software fails to properly manage trusted and untrusted X11 cookies.

Successfully exploiting this issue allows local attackers to potentially launch a forwarded X11 session through SSH in an unauthorized manner. Further details are currently unavailable. We will update this BID as more information emerges.

This issue affects OpenSSH 4.6; previous versions may be affected as well.
