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.

From manual page:

              -r      Enables  the  restricted  shell.   This option cannot be
                      unset once set.

  But one can exit it with:

$ set +r

  One can work an a restricted shell with:

+ Create a ~/.profile that sets PATH to, for example, /rbin
+ Add symbolic links to /rbin, e.g.
  # ln -sf /bin/ls /rbin
+ Remove any unwanted environment variable or function from
  ~/.profile with unset.

  Above works with bash, on basic tests using .bash_profile:

export PATH=/rbin
unset command_not_found_handle

and user shell set to /bin/rbash

  Restricted shells overall are somewhat of a fragile solution,
but if the environment is really very small, it is a somewhat
safe option.

Upstream commit: https://github.com/ksh93/ksh/commit/74b4162178c8a2347491b9fd3a22d8e6e1b7e831

Thus this bug is fixed in ksh on all versions of rhel-9 and higher.
