Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:	.Pulling images from the quay.io registry no longer leads to unintended images Previously, having the quay.io container image registry listed in the default registries search list provided in `/etc/containers/registries.conf` could allow a user to pull a spoofed image when using a short name. To fix this issue, the quay.io container image registry has been removed from the default registries search list in `/etc/containers/registries.conf`. As a result, pulling images from the `quay.io` registry now requires users to specify the full repository name, such as `quay.io/myorg/myimage`. The quay.io registry can be added back to the default registries search list in `/etc/containers/registries.conf` to reenable pulling container images using short names, however, this is not recommended as it could create a security risk.

Description Jason Shepherd 2019-12-17 06:38:25 UTC

Description of problem:

Having multiple public repositories in the list can lead to typosquatting and supply chain attacks against Red Hat customers.


Version-Release number of selected component (if applicable):

container-tools-1:0.1.37-5.module+el8.1.0+4240+893c1ab8
From repo: rhel-8-for-x86_64-appstream-rpms

How reproducible:

$ cat /etc/containers/registries.conf | grep registries.search -A 1


Actual results:

[registries.search]
registries = ['registry.access.redhat.com', 'docker.io', 'registry.fedoraproject.org', 'quay.io', 'registry.centos.org']


Expected results:

[registries.search]
registries = ['registry.access.redhat.com', 'docker.io', 'registry.fedoraproject.org', 'registry.centos.org']
