Description Mark J. Cox (Product Security) 2006-09-27 18:53:53 EDT
Tavis Ormandy of the Google Security Team discovered a denial of service attack
on the openssh sshd daemon when ssh protocol version 1 is enabled.  This flaw
will cause the openssh server to consume a large quantity of the CPU until the
specified timeout is reached.
