Synopsis: ELSA-2016-2006 can now be patched using Ksplice
CVEs: CVE-2016-4470 CVE-2016-5829

Systems running RHCK on Oracle Linux 6, Red Hat Enterprise Linux 6,
CentOS 6, and Scientific Linux 6 can now use Ksplice to patch against
the latest Red Hat kernel update, ELSA-2016-2006.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on OL 6, RHEL 6, CentOS
6, and Scientific Linux 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-2016-4470: Denial-of-service in the keyring subsystem.

Failure to check that a key was properly added to a keyring before removing
it could lead to a kernel crash.  A local, unprivileged user could use this
flaw to cause a denial-of-service.


* CVE-2016-5829: Memory corruption in unknown USB HID devices.

The USB HID driver does not validate USB data when an unknown HID device
is encountered which can allow a malicious USB device to trigger kernel
memory corruption and gain execution.


* Denial-of-service when resetting a Fibre Channel over Ethernet interface.

Lack of input validation when extracting the CPU number from a Fibre
Channel over Ethernet (FCoE) header could lead to a kernel crash when
resetting a FCoE interface.  A local user with the ability to reset such
interface could use this flaw to cause a denial-of-service.
