Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Summary:	"sudo -l -U user" may show incorrect privileges for specified user

Fixed In Version:	sudo-1.7.4p5-9.el6_2	Doc Type:	Bug Fix
Doc Text:	The "-l" option is used to list allowed and forbidden commands for the invoking user or for the user specified by the "-U" option. However, previously, the getgrouplist() function incorrectly checked the invoker's group membership instead of the membership of the specified user. Consequently, using the "sudo" command with both the "-l" and "-U" options listed privileges granted to any group the invoker was a member of. The getgrouplist() function has been fixed to properly check the group membership of the intended user rather than checking the invoker's membership. This ensures that the required output is listed when using the "-l" and "-U options.	Story Points:	---
