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,

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2015-8539: Privilege escalation in the keys subsystem when instantiating a key.

A lack of properly initializing a key payload data when the key was
negatively instantiated could lead to memory corruption.  A local user with
the ability to add keys in the keys subsystem could use this flaw to
cause a denial-of-service or escalate privileges.
