Description Karol Babioch 2018-10-23 15:56:10 UTC 
"User" module leaks any data which is passed on as a parameter to ssh-keygen. This could lean in undesirable situations such as passphrases credentials passed as a parameter for the ssh-keygen executable. Showing those credentials in clear text form for every user which have access just to the process list.

Comment 2 Joseph Davis 2018-11-09 18:11:41 UTC 
SOC 8 is using ansible 1.9.6 in production, which is not listed in the https://www.securityfocus.com/bid/105700 page.

It looks like RH just patched versions 2.5, 2.6, and 2.7.
Comment 3 Joseph Davis 2018-11-09 18:25:16 UTC 
Also Ansible upstream only patched the 2.x versions.
https://github.com/ansible/ansible/pull/47436
Comment 4 Fergal Mc Carthy 2018-11-09 18:50:14 UTC 
Looks like RH only patched the "active" ansible versions, e.g. current, and 2 previous versions...

Looking at the user module implementation in ansible 1.9.6 I see the following:

        cmd.append('-N')
        if self.ssh_passphrase is not None:
            cmd.append(self.ssh_passphrase)
        else:
            cmd.append('')

That suggests we have the issue in ansible 1.9.6, and would need to backport the proposed fix to our ansible1 RPM that is used in the SOC/CLM product line.
Comment 5 Joseph Davis 2018-11-09 20:21:01 UTC 
Fergal and I checked our Ansible playbooks and find no uses of the 'ssh_key_passphrase' property (the ssh keys are managed a different way).  Thus for Cloud products the bug is already mitigated.

We can create a patch for the ansible1 project in IBS/OBS to backport the fix, but there isn't any urgency at this time.
