INSTALLING THE UPDATES

OL6 and OL7 install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
* CVE-2018-14678: Privilege escalation in Xen PV guests.
Incorrect register accounting during paravirtualized failsafe callbacks
could result in the use of uninitialized memory and a kernel crash or
potentially escalation of privileges in a paravirtualized guest.
* Improved fix to CVE-2018-3620, CVE-2018-3646: Information leak in Intel CPUs under terminal fault.
The original fix for L1 Terminal Fault/Foreshadow could prevent loading
of microcode when hyperthreading was disabled or failure to mprotect
specific memory mappings.
