Problem Description:

A flaw in OpenSSH prior to 4.7 prevented ssh from properly handling
when an untrusted cookie could not be created and used a trusted X11
cookie instead, which could allow attackers to violate intended policy
and gain privileges by causing an X client to be treated as trusted.

The updated packages have been patched to correct these issue.
