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 Noriko Hosoi 2014-04-11 19:28:30 UTC
Description of problem:
If there is some sort of error in do_search - decoding or protocol errors - after the rawbase variable is allocated but before it is assigned to SLAPI_ORIGINAL_TARGET_DN in pb, the cleanup code will get the NULL variable from the pb and free it, leaking rawbase.

Hi,
how do we verify this? Will be an acceptance/sanity run enough?

Thanks,
Milan

Comment 3 Noriko Hosoi 2014-06-19 16:45:17 UTC
Well, ideally...

Start DS via valgrind.
(Probably, before starting you could prepare the server for the case 2 and 3)

Try following failure case searches.
1. search with invalid base dn
2. Configure the server to prohibit anonymous search.
   Then search anonymously.
3. Configure the server with high minimum SSF.
   Then search with simple auth.

Stop the server and check the valgrind output.
If it does not contain a memleak report having do_search in it, the fix is verified.
