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:
This is a continuation of BZ #1941661.
The rule "xccdf_org.ssgproject.content_rule_selinux_policytype" in scap-security-guide is too strict and also not correct on RHEL7:
linux_os/guide/system/selinux/selinux_policytype/oval/shared.xml:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
28 <ind:textfilecontent54_object id="obj_selinux_policy" version="1">
29 <ind:filepath>/etc/selinux/config</ind:filepath>
30 <ind:pattern operation="pattern match">^[\s]*SELINUXTYPE[\s]*=[\s]*([^\s]*)</ind:pattern>
31 <ind:instance datatype="int">1</ind:instance>
32 </ind:textfilecontent54_object>
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
This states that you can have spaces before and after "=" sign, which is not true because SELINUXTYPE is a shell script variable.
Additionally it expects no trailing space after the value, e.g. "SELINUXTYPE=targeted<space>" will fail, which is the case because /etc/selinux/config ships the file with a trailing space (see BZ #1941661).
Please fix the rule as it was done in Upstream:
linux_os/guide/system/selinux/selinux_policytype/oval/shared.xml:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
24 <ind:textfilecontent54_object id="obj_selinux_policy" version="1">
25 <ind:filepath>/etc/selinux/config</ind:filepath>
26 <ind:pattern operation="pattern match">^SELINUXTYPE=([\w]*)[\s]*$</ind:pattern>
27 <ind:instance datatype="int">1</ind:instance>
28 </ind:textfilecontent54_object>
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
Version-Release number of selected component (if applicable):
scap-security-guide-0.1.52-2.el7_9.noarch
How reproducible:
Always
Steps to Reproduce:
1. On a basic RHEL7 system, execute the rule
# oscap xccdf eval --rule xccdf_org.ssgproject.content_rule_selinux_policytype --profile xccdf_org.ssgproject.content_profile_stig /usr/share/xml/scap/ssg/content/ssg-rhel7-ds.xml
Actual results:
Result fail
