Ok, so I think we need 1 CVE for the two insecure temporary file uses,
unless we want to split each temporary file issue under a separate
CVE. I don't believe there's a real need to assign CVE for 2.4.1
(which did not improve things on systems with world writable /var/lock)
or 2.4.2 (which re-opens the attack for pkcs11 group members on systems
with restricted /var/lock, but improves things on systems with world
writable /var/lock).
