| Doc Text: |
A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely.

Acknowledgments: Name: Damien Aumaitre (Quarkslab), Nicolas Surbayrole (Quarkslab) Is there any futher information on this issue? Is the issue reported upstream, which versions are affected? Created ansible tracking bugs for this issue: Affects: epel-all [bug 1805319] Affects: fedora-all [bug 1805318] Hey Salvatore, I am working to provide additional information regarding this issue; more details as you requested, affected versions as well as upstream links in case we already have. Prioritising this for now, I will get back to you asap. In reply to comment #4: > Is there any futher information on this issue? Is the issue reported > upstream, which versions are affected? Red Hat CloudForms Management Engine 5.9 is in maintenance phase and we're no longer fixing "Low" severity CVEs. Mitigation: Currently, there is no mitigation for this issue except avoid using the 'edit' option from 'ansible-vault' command line tool. Upstream fix: https://github.com/ansible/ansible/issues/67798 Created ansible tracking bugs for this issue: Affects: openstack-rdo [bug 1807880] 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. This issue has been addressed in the following products: Red Hat Ansible Engine 2.9 for RHEL 7 Red Hat Ansible Engine 2.9 for RHEL 8 Via RHSA-2020:1541 https://access.redhat.com/errata/RHSA-2020:1541 This issue has been addressed in the following products: Red Hat Ansible Engine 2 for RHEL 7 Red Hat Ansible Engine 2 for RHEL 8 Via RHSA-2020:1542 https://access.redhat.com/errata/RHSA-2020:1542 This issue has been addressed in the following products: Red Hat Ansible Engine 2.8 for RHEL 7 Red Hat Ansible Engine 2.8 for RHEL 8 Via RHSA-2020:1543 https://access.redhat.com/errata/RHSA-2020:1543 This issue has been addressed in the following products: Red Hat Ansible Engine 2.7 for RHEL 7 Via RHSA-2020:1544 https://access.redhat.com/errata/RHSA-2020:1544 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-1740 CloudForms 5.11 do not use ansible-tower and 5.10 only using ansible-tower-venv-ansible atm. 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. |
