CVEs: CVE-2016-8630 CVE-2016-8655 CVE-2016-9083 CVE-2016-9084

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2017-0386.


We recommend that all users of Ksplice Uptrack running RHCK 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


* CVE-2016-9083, CVE-2016-9084: Integer overflow in PCI VFIO bus driver.

An error in user-supplied arguments sanitizing of VFIO_DEVICE_SET_IRQS
ioctl could lead to an integer overflow. A local user with capability to
use this ioctl could cause a denial-of-service.

* CVE-2016-8655: Privilege escalation in af_packet implementation.

A race condition in af_packet processing could allow a local
unprivileged user to cause a kernel crash or execute arbitrary code
with elevated privileges.

* CVE-2016-8630: NULL pointer dereference in KVM instruction decoding.

A missing check during instruction decoding operations could lead to a
NULL pointer dereference. An attacker from a Virtual Machine could
inject instructions with specific properties to cause a
denial-of-service of the host.


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