Question: Is it possible to limit yum so that it lists or installs only security updates? How to patch the system only with security errata ?
Answer :
Install the yum-security plugin
It is now possible to limit yum to install only security updates (as opposed to bug fixes or enhancements) by installing the yum-security plugin. Contrary to RHEL 7, in RHEL 6 the yum-security plugin is not part of yum. So to install the plugin use :
# yum update-minimal -security -y To only install the packages that have a security errata use # man yum-security For more commands consult the manual pages of yum-security with Note: you will be able to run these commands with yum 'updateinfo' when you have installed 'yum install yum-plugin-security' on centOS 6.
