I was recently using scap-workbench on RHEL7 to secure the > system. After applying fix for CCE-27291-4 (add 'session required > pam_lastlog.so showfailed') to /etc/pam.d/system-auth, scap-workbench > immediately begins throwing an error when attempting to scan the system: > "ERROR: pkexec.c:142:pam_conversation_function code should not be reached" I can reproduce the issue you are experiencing. That error / warning message is a result of invalid PAM /etc/pam.d/system-auth configuration. Have checked the recommendation with PAM developers and the conclusion being that on RHEL-7 and Fedora systems the setting shouldn't be applied into /etc/pam.d/system-auth file, but rather against / into /etc/pam.d/postlogin PAM file. I will submit a PR changing the OVAL check && XCCDF recommendation for RHEL-7 and Fedora products (so future SSG versions aren't prone to this bug).

Thank you again for your report! Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Technologies Team > > Any thoughts?
