Subject: CVE-2010-2960 kernel: keyctl_session_to_parent null ptr deref

Patches (not in upstream yet):
https://bugzilla.redhat.com/show_bug.cgi?id=627440#c4
https://bugzilla.redhat.com/show_bug.cgi?id=627440#c5

You might need to comment out all the pam_keyinit calls in /etc/pam.d/

affected.

Introduced via upstream commit ee18d64c (v2.6.32-rc1).
