The packages, as of the last night's cron jobs, are typically in
"/var/log/rpmpkgs", generated by the "/etc/cron.daily/rpm" script.
That script is not mandatory and does not seem to be in RHEL 6 nor
will it therefore be in CentOS 6, but lord, it's useful in this kind
of situation. It's also much faster to parse, than manually issuing
"yum" commands.
