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.

+++ This bug was initially created as a clone of Bug #717338 +++

Description of problem:
When my application attempts to load a private key file, it crashes in pem_CreateObject().

Version-Release number of selected component (if applicable):
nss-3.12.10-4.fc16.x86_64

How reproducible:
Always

Steps to Reproduce:
1. SECMOD_LoadUserModule(libnsspem.so)
2. PK11_CreateGenericObject(CKA_CLASS=CKO_PRIVATE_KEY,CKA_TOKEN=CK_TRUE)
  
Actual results:
pem_CreateObject() passes an uninitialized certDER.data to nss_ZFreeIf()

Additional info:
When I cut it down to the bare minimum to try to create a simpler reproducer, I don't get a crash any more, but valgrind at least still flags the errors.

Nalin, I'm picking up your patch. It will be applied with other I have in the queue. Thanks.

I was comparing the sources after all approved patches had been applied to RHEL 6.3 and Fedora and I noticed that we are missing this one. I recommend picking this up for RHEL 6.3.

Intialize the pointer to NULL

This is Nalin' patch updated so it applies after all the other patches.

Elio, can you attack a pointer to the full pobject.c The given context is not enough to review the patch.

Thanks.

Aha, looking at the bigger context I realized the patch needs a bit more work.
