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the product is no longer active in Red Hat Bugzilla.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 of problem:
In /etc/login.defs, there is a variable PASS_MIN_LEN which would appear to set a minimum length for passwords. It is read by only one function in all of shadow-utils. This function is only used by the shadow-utils version of passwd. RHEL and Fedora ship an entirely different passwd program which uses pam to determine the minimum password length. Therefore, any rules that look at or change this setting is entirely unneeded.
Additional info:
These might be the rules to look into:
- var_accounts_password_minlen_login_defs=12
- accounts_password_minlen_login_defs
They can safely be dropped in all content aimed at RHEL & Fedora. I think there may be other distributions which ship the shadow-utils passwd program. If you find any, just allow these rules in their content.
As Steve has already pointed out PASS_MIN_LEN is only used by the shadow-utils passwd, and this binary isn't shipped in RHEL and Fedora. Thus I think that the rule can be removed.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory (scap-security-guide bug fix and enhancement update), and where to find the updated
files, follow the link below.
