Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Description Jan Pazdziora (Red Hat) 2021-11-17 10:19:38 UTC 
Description of problem:

The /usr/lib/s390-tools/cpictl is installed with permissions 0775 (group writable). That means that should the admin use the root group for something special, they would allow modifying this script to users in that group.

And looking at

# ls -la /usr/bin | grep '^-rwxrwx' | wc -l
0

other packages don't package binaries that way.

Checking the .spec file, it is not explicitly set, so it looks like some glitch in the source / build process.

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

s390utils-core-2.17.0-4.el9.s390x

How reproducible:

Deterministic.

Steps to Reproduce:
1. ls -la /usr/lib/s390-tools/cpictl | grep '^-rwxr-x'

Actual results:

Nothing returned.

Expected results:

-rwxr-xr-x. 1 root root 6356 Aug 10 12:16 /usr/lib/s390-tools/cpictl

-rwxrwxr-x. 1 root root 6356 Nov  9 03:27 /usr/lib/s390-tools/cpictl
# rpm -qa | grep s390utils
s390utils-core-2.18.0-1.el9.s390x
# dnf upgrade s390utils-core-2.19.0-1.el9.s390x.rpm
(...)

Comment 7 jschinta 2022-03-22 14:42:12 UTC 
Hi,

i wanted to ask if there are plans to backport this fix to RHEL 8.6 through RHEL 8.4. I can find the same issue there.

currently there is no such plan, but the upstream fix will be part of the s390utils rebase in 8.7
