I've been staying out of this because I'm not sure of where this is
headed.

Red Hat / CentOS packaging changelogs can be inspected by doing things
like 

(remote packages)
 rpm -qp --changelog \
ftp://ftp.redhat.com/pub/redhat/linux/updates/enterprise/4ES/en/os/SRPMS/kernel-2.6.9-22.EL.src.rpm

(installed packages)
rpm -q --changelog httpd

and of course you could grep the output for specific advisories...

# rpm -q --changelog httpd | grep CVE-2005-2700
- mod_ssl: add security fix for SSLVerifyClient (CVE-2005-2700)

or you could probably dump all the changelogs of all installed packages
into a text file and grep away...

rpm -qa --changelog > /tmp/changelogs.txt

so I'm not really sure that is everything Jeremy was looking for but
certainly an answer to Hans' doubt.
