AIX OpenSSH Advisory : openssh_advisory2.asc

Synopsis :

The remote AIX host is running a vulnerable version of OpenSSH.

Description :

The version of OpenSSH running on the remote host is affected by a
denial of service vulnerability. The default configuration of OpenSSH
through 6.1 enforces a fixed time limit between establishing a TCP
connection and completing a login, which makes it easier for remote
attackers to cause a denial of service (connection-slot exhaustion)
by periodically making many new TCP connections.

Solution :

A fix is available, and it can be downloaded from the AIX website.

IMPORTANT: If possible, it is recommended that a mksysb backup of
the system be created. Verify it is both bootable and readable
before proceeding.

To preview the fix installation:
installp -apYd . OpenSSH_6.0.0.6102
