Systems running Virtuozzo 4.7 or the OpenVZ RHEL 6 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers 4.7

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Virtuozzo 4.7
or OpenVZ on RHEL 6 install these updates.

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


DESCRIPTION

* CVE-2018-14634: Privilege escalation in ELF executables.

An integer overflow in the argument setup for a new ELF executable could
result in attacker controlled corruption of the user stack when
executing a SUID binary.  A local, unprivileged user could use this flaw
to gain superuser privileges.


Ksplice will not be providing a zero-downtime update for CVE-2018-5391, 
customers needing mitigation against this vulnerability should reboot 
into the latest kernel release.
