Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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.

Description Stephen Wadeley 2021-06-04 08:46:08 UTC 
Description of problem:

After running automated tests I found:

 ~]# ausearch -m AVC,USER_AVC -ts today
----
time->Fri Jun  4 09:36:43 2021
type=PROCTITLE msg=audit(1622792203.625:40405): proctitle=7368002D630073797374656D63746C2069732D656E61626C65642070756C70636F72652D6170692E7365727669636520263E2F6465762F6E756C6C

Version-Release number of selected component (if applicable):
 ~]# rpm -q satellite
satellite-6.9.2-1.el7sat.noarch

How reproducible:
I see three AVCs today

Steps to Reproduce:
1. Install Sat6.9.2
2. Run some Robottelo tests over SSH (I was running: tests/foreman/ui/test_contenthost.py::test_positive_end_to_end)
3. Run tests/foreman/sys/test_pulp3_filesystem.py::test_selinux_status

Actual results:
SSHCommandResult(stdout=['type=AVC msg=audit(1622792203.625:40405): avc:  denied  { getattr } for  pid=15582 comm="sh"...070756C70636F72652D6170692E7365727669636520263E2F6465762F6E756C6C', ''], stderr=b'', return_code=0, output_format=None).return_code

Expected results:
No AVC
Comment 3 Lukas Zapletal 2021-06-04 11:53:48 UTC 
This is likely caused by https://github.com/Katello/katello/blob/7c9aa78fb5c5c14ea15af759a9d36fd4a7368377/app/models/katello/ping.rb#L12 which was added recently. We cannot allow executing this command, therefore the code must be updated in Katello.
