Keep in mind: when using the yum-plugin-security package which provides the --security option, you're only going to see security updates in EPEL (which I see you have enabled) and not in CentOS's repos. As of yet, there are no errata data in the CentOS repos. See previous discussion here: http://lists.centos.org/pipermail/centos/2015-January/148839.html and on centos-devel: http://lists.centos.org/pipermail/centos-devel/2014-September/011893.html So, --security is pretty much a no-op, even when there are packages that fix security issues are available in the CentOS repos. -- Jonathan Billings <billings at negate.org>
