Systems running Virtuozzo 4 or the OpenVZ RHEL 5 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers
kernel security update, CVE-2016-5195.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Virtuozzo 4 or
OpenVZ on RHEL 5 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

otherwise read-only memory mappings.  A local, unprivileged user could use
this flaw to escalate their privileges.
