(RHSA-2023:0742) Low: RHUI 4.3.0 release - Security Fixes, Bug Fixes, and Enhancements Update

Red Hat Update Infrastructure (RHUI) offers a highly scalable, highly redundant framework that enables you to manage repositories and content. It also enables cloud providers to deliver content and updates to Red Hat Enterprise Linux (RHEL) instances.

Security Fix(es):

• Django: Potential bypass of an upstream access control based on URL paths (CVE-2021-44420)

• Django: Potential denial-of-service vulnerability in internationalized URLs (CVE-2022-41323)

This RHUI update fixes the following bugs:

• Previously, rhui-manager failed to create an Alternate Content Source package. With this update, the problem is now fixed and you can successfully create an Alternate Content Source package.

• With this update, several parts of redundant code have been removed from RHUI. Most notably, the unused entitlement argument in the custom repository creation has been removed. Additionally, the Atomic and OSTree functions have been removed because these features have been deprecated in RHUI 4.

• Previously, CDS and HAProxy management used a variable called port. However, this name is a reserved playbook keyword in Ansible. Consequently, Ansible printed warnings about the use of this variable. With this update, the variable has been renamed to remote_port which prevents the warnings.

• Previously, when the RHUA installation playbook failed, rhui-installer exited with a status of 0, which normally indicates success. With this update, the problem has been fixed, and rhui-installer exits with a status of 1, indicating that the RHUA installation playbook has failed.

• Previously, RHUI did not accept proxy server settings when adding container images. Consequently, RHUI was unable to synchronize container images if the proxy server configuration was required to access the container registries. With this update, RHUI now accepts proxy settings when they are configured with the container images. As a result, proxy-enabled RHUI environments can now synchronize container images.

• With this update, the misaligned text on the repository workflow screen in the rhui-manager text interface has been fixed.

This RHUI update introduces the following enhancements:

• This update introduces a newer version of Pulp, 3.21.0. Among other upstream bug fixes and enhancements, this version changes how Pulp manages ambiguous CDN repodata that contains a duplicate package name-version-release string. Instead of failing, Pulp logs a warning and allows the affected repository to be synchronized.(BZ#2134277)

• A new rhui-manager command is now available, rhui-manager [--noninteractive] cds reinstall --all. With this command, you can reinstall all of your CDS nodes using a single command. Additionally, you do not need to specify any of the CDS host names.
