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.

Red Hat Product Errata RHBA-2017:2083 0 normal SHIPPED_LIVE python-rhsm and subscription-manager bug fix and enhancement update 2017-08-01 18:14:19 UTC

Description Jiri Hnidek 2017-05-15 08:51:31 UTC 
Description of problem:
File com.redhat.SubscriptionManager.policy currently allows any local user to open a popup on a user logged in graphic mode. The popup will contain warnings about subscription/entitlements status, but it does not allow any modifications.

Version-Release number of selected component (if applicable):
[root@rhel74 ~]# subscription-manager version
server type: Red Hat Subscription Management
subscription management server: 0.9.51.21-1
subscription management rules: 5.15.1
subscription-manager: 1.19.12-1.el7
python-rhsm: 1.19.6-1.el7

How reproducible:
always

Steps to Reproduce:
1. Install build RHEL-7.4-20170504.0 with gnome desktop environment
2. Login using gdm (as not root, but common user)
3. Open gnome-terminal
4. Switch to another user using su command.
5. Run following command in terminal:

busctl call com.redhat.SubscriptionManager /EntitlementStatus com.redhat.SubscriptionManager.EntitlementStatus update_status i <status_num>

status_num can be any number in range: 0-5

Actual results:
Popup window will appear.

Expected results:
No popup window appear, because common user should not be able to trigger this method.

Additional info:
Common user could be able to get status of entitlement using:

busctl call com.redhat.SubscriptionManager /EntitlementStatus com.redhat.SubscriptionManager.EntitlementStatus check_status
