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 Joe Wright 2015-05-12 22:04:29 UTC 
Description of problem:
- openscap-scanner segfault

Version-Release number of selected component (if applicable):
- openscap-scanner-1.1.1-3.el7

How reproducible:
- intermittent

Steps to Reproduce:
oscap xccdf eval --profile test /home/schachingerx/scap-security-guide/RHEL/7/output/ssg-rhel7-xccdf-copy.xml

...results in this (majority of output omitted) :

Title   Set SSH Idle Timeout Interval
Rule    sshd_set_idle_timeout
Ident   CCE-26611-4
Result  pass

Segmentation fault (core dumped)
[root@schachinger Documents]#

Sometimes I get an abrt notification but sometimes I don't. I can correct this error by commenting out the following lines under the "test" profile in my XCCDF XML file (attached to case)
    <select idref="account_disable_post_pw_expiration" selected="false"/>
    <select idref="accounts_passwords_pam_faillock_deny" selected="false"/>
    <refine-value idref="var_password_pam_unix_remember" selector="4"/>
    <refine-value idref="var_account_disable_post_pw_expiration" selector="90"/>
    <refine-value idref="var_accounts_passwords_pam_faillock_deny" selector="6"/>
    <refine-value idref="var_password_pam_minlen" selector="7"/>

Actual results:
- segfault

Expected results:
