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 Rajesh Dulhani 2023-08-30 19:43:54 UTC
Description of problem:

The SCAP check xccdf_org.ssgproject.content_rule_sudo_custom_logfile is failing on the correctly working sudo configuration that defines the logfile:

Snippet from /etc/sudoers
~~~
Defaults logfile = /var/log/sudo
Defaults loglinelen = 0
~~~

The problem is the missing whitespace handling before and after the '='. This is clearly visible in the Pattern used: '^[\s]*Defaults[\s]*\blogfile=("(?:\\"|\\\\|[^"\\\n])*"\B|[^"](?:(?:\\,|\\"|\\ |\\\\|[^", \\\n])*)\b).*$' that has no whitespace pattern before and after the '=' character

Bug is still present in the latest 0.1.69 version freshly released a few hours ago for 8.6-EUS.

How Reproducible:

reproducer is to add the snippet above to /etc/sudoers and run the CIS-L1 scap check and notice that the sudo logfile rule is failing


Version-Release number of selected component (if applicable):
Package - openscap-1.3.8-1.el8_6.x86_64.rpm


Actual results:

Incorrect security reporting for a valid configuration causing leading to discussions why the rule failed.
