Linux - limit yum so that it lists or installs only security updates


The plugin is already a part of yum itself, no need to install anything.

For Red Hat Enterprise Linux 6

Raw
# yum install yum-plugin-security

For both Red Hat Enterprise Linux 5, 6, and 7

  • To list all available security updates with verbose descriptions of the issues they apply to:
Raw
# yum info-sec
  • Run the following command to download and apply all available security updates from Red Hat Network hosted or Red Hat Network Satellite:
Raw
# yum -y update --security

NOTE: It will install the last version available of any package with at least one security errata thus can install non-security erratas if they provide a more updated version of the package.

  • To only install the packages that have a security errata use
Raw
# yum update-minimal --security -y
  • yum-security also allows installing security updates based on the CVE reference of the issue. To install a security update using a CVE reference run:
Raw
# yum update --cve <CVE>

e.g.

Raw
# yum update --cve CVE-2008-0947
