=====================================================================

1. Summary:

An updated version of Red Hat Update Infrastructure (RHUI) is now
available. RHUI 4.5 fixes several security and operational bugs and also
adds several new features.

2. Relevant releases/architectures:

RHUI 4 for RHEL 8 - noarch

3. Description:

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 validation when uploading multiple files
using a single form field (CVE-2023-31047)

* sqlparse: Parser contains a regular expression that is vulnerable to
ReDOS (Regular Expression Denial of Service) (CVE-2023-30608)

This RHUI update fixes the following bugs:

* Previously, the `rhui-manager` command used the `logname` command to
obtain the login name. However, when `rhui-manager` is run using the
`rhui-repo-sync` cron job, a login name is not defined. Consequently,
emails sent by the cron job contained the error message `logname: no login
name`. With this update, `rhui-manager` does not obtain the login name
using the `logname` command and the error message is no longer generated.

* Previously, when an invalid repository ID was used with the
`rhui-manager` command to synchronize or delete a repository, the command
failed with following error:
`An unexpected error has occurred during the last operation.`
Additionally, a traceback was also logged. 
With this update, the error message has been improved and failure to run no
longer logs a traceback.

This RHUI update introduces the following enhancements:

* With this update, the client configuration RPMs in `rhui-manager` prevent
subscription manager from automatically enabling `yum` plugins. As a
result, RHUI repository users will no longer see irrelevant messages from
subscription manager. (BZ#1957871)

* With this update, you can generate machine-readable files with the status
of each RHUI repository. To use this feature, run the following command:
`rhui-manager --non-interactive status --repo_json <output file>`
 (BZ#2079391)

* With this update, the `rhui-manager` CLI command uses a variety of unique
exit codes to indicate different types of errors. For example, if you
attempt to add a Red Hat repository that has already been added, the
command will exit with a status of 245. However, if you attempt to add a
Red Hat repository that does not exist in the RHUI entitlement, the command
will exit with a status of 246. For a complete list of codes, see the
`/usr/lib/python3.6/site-packages/rhui/common/rhui_exit_codes.py` file.

4. Solution:
