CentOS - Jul 2011 - No announcement for 4.9 kernel and ypbind?

Can't seem to find a CEBA for the bug fixes for the kernel and ypbind
for CentOS-4. Upstream bug reports can be found here:

kernel-2.6.9-101.EL:
https://rhn.redhat.com/errata/RHBA-2011-0968.html

ypbind-1.17.2-17.el4_8:
http://rhn.redhat.com/errata/RHBA-2011-0955.html

Regards,
Leonard.
