Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in Ansible Engine. When a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.

Comment 9 Yadnyawalk Tale 2020-02-20 22:45:06 UTC 
Red Hat CloudForms Management Engine 5.9 is in maintenance phase and we're no longer fixing "Low" severity CVEs.
Comment 12 Borja Tarraso 2020-02-25 14:58:46 UTC 
Mitigation:

Instead of using the parameter 'password' of the subversion module, provide the password with stdin.

Comment 16 Hardik Vyas 2020-03-18 16:24:35 UTC 
Red Hat Gluster Storage and Red Hat Ceph Storage no longer maintains its own version of Ansible. The fix will be provided from core Ansible. But we still ship ansible separately for ceph ubuntu.

Comment 24 Yadnyawalk Tale 2020-05-11 09:46:42 UTC 
CloudForms 5.11 do not use ansible-tower and 5.10 only using ansible-tower-venv-ansible atm.
Comment 25 Summer Long 2021-01-14 05:02:30 UTC 
Statement:

Ansible Engine 2.7.16, 2.8.10, and 2.9.6 as well as previous versions are affected.

Ansible Tower 3.4.5, 3.5.5 and 3.6.3 as well as previous versions are affected.

In Red Hat OpenStack Platform, because the flaw has a lower impact,  ansible is not directly customer exposed, and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP ansible package.
