Cherry-picking updates is not supported by CentOS, this is because each package is built on a system with all previous updates applied and as such each update that you install should have all previous updates applied or there can be problems. As such CentOS does not support the --security option for yum, nor does it support the yum-security plugin. You are expected to update your entire system, not to do so will leave you with an unsupported system. Also there will be other packages as well that have security issues that need updating. Peter
