Synopsis: ELSA-2018-4244 can now be patched using Ksplice
CVEs: CVE-2018-17182

Users with Oracle Linux Premier Support can now use Ksplice to patch

these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y
