Synopsis: 2.6.32-042stab130.1 can now be patched using Ksplice
CVEs: CVE-2018-3639
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
kernel security update, 2.6.32-042stab130.1.
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-2018-3639: Speculative Store Bypass information leak.
A hardware sidechannel with speculative stores could allow a malicious,
unprivileged user to leak the contents of privileged memory.
This update enables the speculative store bypass mitigation by default
when supported microcode is loaded and can be manually enabled/disabled
by writing 1/0 to /proc/sys/vm/ksplice_ssbd_control. The
/proc/sys/vm/ksplice_ssbd_status file reports the current mitigation
status.
SUPPORT
Ksplice support is available at ksplice-support_ww at oracle.com.
