Re: SSH Vulnerability Fix for AIX?

Actually, IBM does support OpenSSH from the Linux Toolbox for 4.3.3 and
developers site for 5.1.

If you have a support agreement, you can all in on it. They will help you.

According to IBM tech support, there will never be other than a patched
3.4p1 for 4.3.3, or 3.6.1p2 for 5.1.

There should be a new patched version available today that addresses the
latest vulnerability.

As long as SSH is NOT AN OFFICIAL PRODUCT from IBM, it does not have any
support, unless from the Open SSH project page. The link you've sent has the
apropriated solution for this vulnerability issue:

Subject: OpenSSH Security Advisory: buffer.adv

This is the 2nd revision of the Advisory.

This document can be found at: http://www.openssh.com/txt/buffer.adv

1. Versions affected:

       All versions of OpenSSH's sshd prior to 3.7.1 contain buffer
       management errors. It is uncertain whether these errors are
       potentially exploitable, however, we prefer to see bugs
       fixed proactively.

       Other implementations sharing common origin may also have
       these issues.

2. Solution:

                Upgrade to OpenSSH 3.7.1 or apply the following patch.

So, if you're running a version older than 3.7.1, just make an upgrade for
this version. It's a matter of spending some extra minutes reading the
advise.

Does anyone know if IBM (or related) has released an AIX fix for the
new security vulnerability for SSH?

Here is the description of the issue:
