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.

Created attachment 1669263 [details]
The end of backtrace for endless recursion

To get the backtrace it is better to decrease the stack size, for example with `ulimit -s 128` so the backtrace is not so long

Comment 2 Matus Marhefka 2020-03-11 12:54:13 UTC
The issue is caused by infinite recursion where extend_definition references itself in the OVAL. This causes that openscap will eventually reach the stack limit per process (ulimit -s) and it is killed by the kernel. Anyway, openscap should not segfault in any case so this needs to be fixed (e.g. by adding a limit for the extend_definition).

Comment 4 Jan Černý 2020-10-02 09:45:02 UTC
Fixed upstream in https://github.com/OpenSCAP/openscap/pull/1610.
