New Ksplice updates for RHCK 7 (ELSA-2019-2829-01)

Synopsis: ELSA-2019-2829-01 can now be patched using Ksplice
CVEs: CVE-2019-14835

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2019-2829-01.
More information about this errata can be found at
https://linux.oracle.com/errata/ELSA-2019-2829-01.html

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running RHCK 7 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-2019-14835: Privilege escalation during live migration of guest.

A failure to check for guest creating a zero length queue in the vhost driver
can lead to a buffer overflow in the host kernel. A guest virtual machine
could use this flaw to crash the host or potentially escalate privileges when
the virtual machine is live migrated.

Orabug: 30312787

SUPPORT

Ksplice support is available at ksplice-support_ww@oracle.com.
