[Ksplice][Ubuntu-16.04-Updates] New updates available via Ksplice (4.4.0-31.50)

[Oracle Ksplice]

Synopsis: 4.4.0-31.50 can now be patched using Ksplice

Systems running Ubuntu 16.04 Xenial can now use Ksplice to patch
against the latest Ubuntu kernel update, 4.4.0-31.50.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 16.04 Xenial
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

* Denial-of-service in USB HID event handling.

Missing validation in the HID event handling could result in
out-of-bounds memory accesses.  An attacker with physical access to the
system could use this flaw to trigger a denial-of-service.


* Use after free when mounting BPF filesystem in namespace.

The Berkeley Packet Filter allows mounting a filesystem interface in
namespaces which can trigger a kernel panic because of incorrect
reference counting.
